Capabilities of JavaScript Developers

JavaScript developers play a critical role in building dynamic, interactive web applications. Our experts harness the versatility of JavaScript to develop scalable, responsive solutions—whether for front-end interfaces or full-stack architectures. By optimizing user experience and enhancing performance, they help drive tangible improvements in business outcomes.

Interactive Web Interfaces

JavaScript’s core strength is creating highly engaging user interfaces. Toptal developers build dynamic, interactive interfaces using JavaScript, incorporating real-time updates, animations, and responsive design to deliver an exceptional user experience that keeps visitors engaged.

Single-page Application (SPA) Development

Single-page applications allow users to navigate a site without page reloads, providing a fast and seamless browsing experience. Our developers specialize in creating responsive SPAs with JavaScript frameworks, designing and building web applications that are efficient and user-friendly.

Asynchronous Operations

JavaScript is often used for asynchronous tasks, like data loading or fetching external resources. Our developers expertly manage these operations using promises, async/await, and callback functions to ensure that data loads smoothly without slowing down your application.

Frameworks and Libraries

Frameworks and libraries streamline development by offering reusable components and structured architecture. Toptal experts leverage JavaScript libraries like React, Angular, and Vue.js to build scalable and maintainable web applications, ensuring clean, modular code that’s easy to expand and manage.

Integrating APIs for Data Fetching

Efficient data fetching is critical to smooth application performance. Our developers integrate RESTful and GraphQL APIs into your web applications to enable real-time data synchronization between the front end and back end, ensuring fast and reliable communication.

Progressive Web App (PWA) Development

Progressive Web Apps (PWAs) combine the best features of web and mobile applications, delivering an app-like experience directly through the browser. Toptal developers build PWAs using JavaScript to enable offline functionality, push notifications, and faster load times, giving users a seamless experience even without internet access.

Cross-browser Compatibility

To reach a broad audience, web applications must perform consistently across various browsers that may interpret JavaScript differently. To verify that your app works smoothly for all users, our developers ensure cross-browser compatibility by thoroughly testing and addressing any differences in how browsers render JavaScript.

Real-time Features With WebSockets

Real-time functionality, like live chat, notifications, and collaborative tools, allows users to receive updates and interact with content instantly, without needing to refresh the page. Our experts implement WebSockets to build real-time features that deliver instant updates and interactions, making your web application more interactive and responsive.

Form Validation and User Input Handling

Ensuring that user input is valid and accurate is essential for maintaining data integrity. Our developers implement client-side form validation using JavaScript, preventing submission errors and making certain that all data sent to your servers is clean and correctly formatted.

Performance Optimization

Speed is critical to the user experience and user retention. In order to provide a smooth and responsive user experience, Toptal developers optimize JavaScript code by reducing file sizes, implementing lazy loading for faster page load times, and using techniques to minimize performance bottlenecks.

FAQs

  • How much does it cost to hire a JavaScript developer?

    The cost associated with hiring a JavaScript developer depends on various factors, including preferred talent location, complexity and size of the project you’re hiring for, seniority, engagement commitment (hourly, part-time, or full-time), and more. In the US, for example, Glassdoor’s reported average total annual pay for JavaScript developers is $154,000 as of August 2024. With Toptal, you can speak with an expert talent matcher who will help you understand the cost of talent with the right skills and seniority level for your needs. To get started, schedule a call with us — it’s free, and there’s no obligation to hire with Toptal.

  • Typically, you can hire JavaScript developers with Toptal in about 48 hours. For larger teams of talent or Managed Delivery, timelines may vary. Our talent matchers are highly skilled in the same fields they’re matching in—they’re not recruiters or HR reps. They’ll work with you to understand your goals, technical needs, and team dynamics, and match you with ideal candidates from our vetted global talent network.

    Once you select your JavaScript specialist, you’ll have a no-risk trial period to ensure they’re the perfect fit. Our matching process has a 98% trial-to-hire rate, so you can rest assured that you’re getting the best fit every time.

  • Yes. JavaScript is the de facto front-end standard and also widely used for back-end systems, so JavaScript developers are always in demand. Full-stack developers are especially sought-after, as their arsenal of skills enable them to independently create and manage a website. But they’re not just cost-effective for small and medium-sized businesses. In many cases, having a full-stack developer working with a front-end specialist and a back-end engineer creates a strong team with smooth development, as the full stack can precisely interact with both ends and handle the middle ground, making the whole team more efficient.

  • Besides proficiency with JavaScript and at least one back- or front-end framework, the best JavaScript web developers will follow best practices, know their way around Git, have experience maintaining a production project, and be able to quickly identify and resolve bugs. But their soft skills will also shine: effective communication and stakeholder management, strong attention to detail and a commitment to delivering high-quality work, and adaptability to thrive in the JavaScript ecosystem where frameworks, libraries, and environments are constantly changing. The best JavaScript developers will work confidently but not egoistically in order to effectively collaborate within and between teams.

  • To hire the right JavaScript web developer, it’s important to evaluate a candidate’s experience, technical skills, and communication skills. You’ll also want to consider the fit with your particular industry, company, and project. Toptal’s rigorous screening process ensures that every member of our network has excellent experience and skills, and our team will match you with the perfect JavaScript developers for your project.

  • To properly answer this question, an understanding of the scope of the project is required. If you need to build a front-end-only website (without any database), then you need a front-end developer, who will usually use a framework like React, Angular, Next.js, Ember.js, Vue.js, or Svelte. If you only need to create an API or handle a database, you need a back-end developer, who will be specialized in back-end JavaScript technologies such as Node.js, MeteorJS, Backbone.js, or Express.js. Finally, if you need both front- and back-end developers—or if you’re unsure—a full-stack developer will be the safest option.

    Toptal’s JavaScript (and TypeScript) developers include experts in these technologies who will be able to guide you and help you achieve your project goals.

  • At Toptal, we thoroughly screen our JavaScript developers to ensure we only match you with the highest caliber of talent. Of the more than 200,000 people who apply to join the Toptal network each year, fewer than 3% make the cut.

    In addition to screening for industry-leading expertise, we also assess candidates’ language and interpersonal skills to ensure that you have a smooth working relationship.

    When you hire JavaScript experts with Toptal, you’ll always work with world-class, custom-matched JavaScript developers ready to help you achieve your goals.

  • You can hire JavaScript specialists on an hourly, part-time, or full-time basis. Toptal can also manage the entire project from end-to-end with our Managed Delivery offering. Whether you hire a JavaScript developer for a full- or part-time position, you’ll have the control and flexibility to scale your team up or down as your needs evolve. Our JavaScript developers can fully integrate into your existing team for a seamless working experience.

  • We make sure that each engagement between you and your JavaScript developer begins with a trial period of up to two weeks. This means that you have time to confirm the engagement will be successful. If you’re completely satisfied with the results, we’ll bill you for the time and continue the engagement for as long as you’d like. If you’re not completely satisfied, you won’t be billed. From there, we can either part ways, or we can provide you with another JavaScript developer who may be a better fit and with whom we will begin a second, no-risk trial.
