Why Demand for jQuery Developers Remains Strong Despite Headwinds
Cross-browser compatibility was the most nefarious problem in the history of front-end development—until jQuery solved it. JQuery is an exceptionally good framework and one of the most successful open-source software projects of all time, with upward of 280,000 repositories on GitHub and usage on more than 77% of all websites as of June 2023. If you have a legacy website that requires maintenance, it’s extremely likely that you will need to hire a jQuery developer. WordPress remains highly popular and drives jQuery’s popularity and longevity, and developers in charge of maintaining jQuery believe the transition to alternative technologies will be gradual.
JQuery’s motto is “Write less, do more.” That’s a nod to jQuery’s razor-sharp syntax and the fact that it is cross-browser compatible. But it can also be read as a wisecrack on the role of jQuery in the modern web stack: Although it’s perfectly reasonable to continue using jQuery on sites that rely on it, virtually all new projects should use it less, not more. Even if a user relies on a multitude of browsers, all modern browsers are more competent than those of the 2010s, and new frameworks like React and Vue have emerged to fit modern front-end development. If you are building a new project, you might not need to hire a jQuery developer.
This leaves hiring managers in a difficult position: They may have a genuine need for jQuery talent, but they must hire appropriately to avoid encumbering a codebase with the wrong framework, thereby necessitating the need for jQuery developers for years to come. This jQuery hiring guide aims to inform hiring managers and other stakeholders about the technical aspects of jQuery, its strengths and weaknesses, long-term industry trends, and what prerequisites to look for in candidates at every step of the hiring process.
What attributes distinguish quality jQuery Developers from others?
Regardless of a project’s scope or the size of the team, there are some attributes that a senior jQuery developer should possess that set them apart from mid-level or junior jQuery engineers:
Scale
A junior jQuery developer can sprinkle in a bit of jQuery here and there to power small interactions and features, such as a dropdown menu.
A senior jQuery developer can deliver larger components like data visualization, faceted search, and off-canvas menus that offer a clean UX despite their complexity.
Performance
A junior jQuery developer delivers JavaScript UI elements.
A senior jQuery developer delivers JavaScript UI elements with a sharp eye on performance tools such as Google’s Lighthouse or desktop apps like Activity Monitor, which ships with Mac products.
Accessibility
A junior jQuery developer writes code that works—for them.
A senior jQuery developer writes code that works with accessibility in mind and serves users like people who cannot see the display or use a mouse or keyboard.
Discretion
Any jQuery developer can use jQuery for every JavaScript feature on their project.
A senior jQuery specialist will think critically about whether a framework is necessary and, if so, if jQuery is the optimal choice. To wit, there are two situations where jQuery makes sense: existing projects that use it already or (to a lesser degree) any project that uses a CMS that is likely to bundle jQuery for the long haul. Within those scenarios, the expert will find opportunities to replace jQuery with pure JavaScript. Outside those scenarios, an expert jQuery engineer will have the hands-on experience and judgment necessary to guide the project to an adjacent technology.
Organization
A junior jQuery developer will write code to solve a problem.
A senior jQuery engineer will bundle jQuery code in an organized fashion, such as a jQuery plugin or a class; they can deliver highly robust user-facing modules.
While the shift to alternative technologies—modern JavaScript frameworks or plain JavaScript— is gradual and will likely take years, hiring managers should consider the implications now. Selecting candidates from a large talent pool, narrowing the selection, interviewing the most promising individuals, and onboarding new hires is no small feat. The process involves management and senior engineers, i.e., individuals whose time is valuable and should be used as efficiently as possible. Therefore, candidates with broad skill sets have an advantage when it comes to long-term positions. As jQuery projects wind down, candidates with proven track records of upskilling and adaptability will remain valuable.
The ideal candidate will likely need an array of front-end programming skills—unless a client is hiring a jQuery specialist for a one-off project.
How can you identify the ideal jQuery Developer for you?
How you search for an ideal jQuery engineer will vary depending on the type and scale of the project, whether or not you need to hire a single jQuery developer or team, the amount of legacy code involved, and other factors. Hiring remote jQuery developers may require the consideration of additional factors, such as working across time zones and communicating in multiple languages.
However, a hiring manager will not have to weigh whether to hire a junior or a senior jQuery developer. Because jQuery is a legacy framework—and has stopped adding new features—it makes sense to only hire someone with many years of jQuery experience and strong knowledge of the framework. Developers who are early in their careers are trending toward more modern frameworks such as React, Vue, or Angular. A “junior jQuery developer” is likely to be someone who, in actuality, doesn’t want to work with jQuery but needs to know its basics, even though they focus on modern frameworks.
To identify jQuery experts, start with a problem statement. Describe the problem that needs to be solved in a way that will make sense to someone with no context for your business requirements and limited knowledge of your industry. What is the status of your project or feature now? What would you like it to be?
Be clear about whether or not your project uses jQuery. Explain the larger tech stack around your project: Is it on a popular CMS like WordPress? Does it use any plugins on the front end that include jQuery? Is the codebase organized in a certain way, with crucial front-end modules, and does its structure promote reusable code? These factors tip the scale in favor of using jQuery and will help front-end developers decide if their skill sets are a good fit for your project.
When ubiquitous technology becomes outdated, caveats and gray areas appear. For example, what if a small company launches a spinoff of an existing project built using jQuery? Ten years ago, the new project would repurpose as much existing code as possible with jQuery in tow. However, that approach wouldn’t be a good long-term choice today.
Perhaps management will decide to build the new project from the ground up and use that knowledge to update their core project. Alternatively, they can enlist freelance jQuery developers and work on both projects in parallel. Expert input from seasoned jQuery engineers can be of great value in such scenarios.
Complementary Skills for jQuery Developers
JQuery, as a JavaScript framework, exists as part of the trinity of front-end web development programming languages: JavaScript, CSS, and HTML5. Consider these technical skills when hiring a jQuery developer:
JavaScript – A good jQuery developer should have a deep and continuing education in “vanilla” JavaScript, i.e., JavaScript that does not use any framework. As JavaScript becomes ever more powerful, the role of jQuery shrinks. Your developer should not think of jQuery as their only hammer and your project as yet another nail. Other popular JS frameworks such as React, Vue, and Angular should be considered as well.
CSS – A jQuery developer will likely be responsible for styling newly created components, which will require writing CSS. Here’s a good litmus test: Does the candidate have an opinion—some sort of well-formed, perhaps passionate opinion—on the emerging debate between “semantic class names” versus utility-first CSS, perhaps through a framework like TailwindCSS? There’s no one right answer, but it’s helpful to understand if the candidate takes his craft seriously and has a stake in where it’s going.
HTML5 – A jQuery developer should take seriously the decision of which HTML element to choose for a particular situation because it can have big implications that are not obvious at first. For example, suppose a developer uses a link for a menu show/hide button instead of the HTML button element. This may create a confusing experience for users who navigate with a screen reader.
How to Write a jQuery Developer Job Description for Your Project
A jQuery job description must be clear about whether or not your project relies heavily on jQuery.
Also, note any special concerns around front-end performance tests like Google’s Core Web Vitals, as jQuery can impact those tests. This detail should attract jQuery engineers with extensive experience who’ve optimized and updated sites and know what challenges and pitfalls to expect.
Finally, include some context about the tech stack your project uses. Is it on WordPress? Does it rely on plugins that use jQuery? Are you considering changing the stack in the long run? If so, how?
What are the most important jQuery Developer interview questions?
Because interviewers and candidates typically spend a lot of time preparing for job interviews, creating truly original interview questions is a good practice. Don’t rely on common questions that are just a Google search away. Prepare open-ended questions and be ready to expand on them with follow-ups. Don’t shy away from curveballs. Here is a selection of interview questions to ask when hiring for jQuery development services:
Is jQuery a good fit for every project? Why or why not?
The candidate should recognize that jQuery is inappropriate for new web projects but assert that it’s the best choice when a project already relies on jQuery and a full rewrite is out of scope. Additionally, they should understand that jQuery can have a minor negative impact on performance tests like Google’s Core Web Vitals, so if there’s little margin for error there, jQuery will be a hindrance.
What are some performance concerns related to jQuery? How might you mitigate them?
The candidate should explain that there are two general categories of performance issues:
Loading the jQuery library itself, which should be done as late in the page load as possible so as to not block other assets.
In-browser performance of jQuery, which can be optimized by caching selectors. For example, if developers use jQuery to take a few different actions on every link on the page, select the entire collection of links once, and then re-use that selection for each action. Novice jQuery developers will sometimes repeat the selection process multiple times.
Explain what a jQuery plugin is and whether or not you might write one for this project.
The candidate should explain that a jQuery plugin is a standard way of delivering a jQuery feature so it will be recognizable to other skilled developers. It gives a convenient syntax for applying a given feature to a specific page element while allowing multiple elements on the same page to re-use the same feature (if warranted).
How do you test your work beyond making sure that a given feature seems to work?
The candidate should be accustomed to using Google’s Lighthouse tool to audit for common front-end issues around performance, a11y, and SEO. They deserve bonus points if they mention using a desktop application like Mac’s Activity Monitor to see if they’ve written something that’s taxing the CPU.
What can you tell me about the jQuery UI library?
The candidate should explain that jQuery UI is a collection of helpful user interface elements written in jQuery and maintained by largely the same community as jQuery itself. Many of its implementations, like autosuggests, accordions, and datepickers, are de facto standards.
Why do companies hire jQuery Developers?
Companies hire jQuery developers because jQuery is immensely popular and easy to work with. It’s used on a staggering 77% of websites, and it’s a staple of WordPress development, since it’s used by countless third-party WordPress plugins. Unless a full rewrite is in scope, most modern businesses will find that the continued use of jQuery is a perfectly viable and economical way to keep a successful project on track.
A jQuery engineer can help maintain and improve existing sites, especially in terms of performance, a key SEO metric. In addition, jQuery experts can help future-proof sites to a certain degree, as well as help clients plan ahead, i.e., help them lessen their reliance on jQuery in favor of plain JavaScript and other technologies.
What are the most popular jQuery use cases?
JQuery enables faster development of pages that provide the user with a rich visual experience. Classic examples include a slider, an autosuggest search, and an accordion menu.
Many of these are bundled as well-known jQuery plugins through the excellent jQuery UI library.
Additionally, when a site needs to make an HTTP call to the server (also known as AJAX), jQuery has fantastic syntax.
How can hiring an experienced jQuery developer contribute to the success of a project?
JQuery is very good at Document Object Model (DOM) manipulation and AJAX capabilities. If you have a site or a feature with many moving elements that may require interaction with third-party APIs and websites, jQuery has excellent built-in methods, including those for DOM tree traversal.
An experienced jQuery developer will take a step back from the feature at hand and contribute to a conversation about whether jQuery is appropriate for a project. The best jQuery development process today weans sites off of jQuery and onto vanilla JavaScript.
A jQuery expert will be able to fulfill immediate business needs through the use of jQuery while taking opportunities to migrate away from it when appropriate.
