How many times have you used the find-and-replace functionality (or RegEx) across a directory to make changes to JavaScript source files? Up your refactoring game by using codemods, scripts used to rewrite other scripts.
In this article, Toptal Freelance Developer Jeremy Greer walks us through three common uses of codemods, using the toolkit “jscodeshift.”

Sass Mixins: Keep Your Stylesheets DRY
Nowadays, front-end development workflows involve many modern tools and preprocessors that not only streamline the whole process, but also allow you to spend less time on common web tasks, giving you more time to focus on other aspects of the project that require more careful and skilled insight. Sass, the scripting language for syntactically awesome stylesheets, comes with robust and built-in support for mixins - an essential feature for keeping your stylesheets DRY.
In this article, Toptal Freelance Software Engineer Justin Brazeau shows us 10 useful Sass mixins that help keep your stylesheets manageable by breaking them into smaller reusable bits, each with its own focus.

Declarative Programming: Is It A Real Thing?
In a nutshell, declarative programming consists of instructing a program on what needs to be done, instead of telling it how to do it. This approach involves providing a domain-specific language (DSL) for expressing what the user wants. This DSL shields users from messy low-level constructs while still achieving the desired end-state.
While declarative programming offers advantages over the imperative approach it replaces, it’s not as straightforward as it may seem. In this comprehensive article, Toptal Freelance Software Engineer Federico Pereiro outlines his experience with declarative tools and explains how you can make declarative programming work for you.

Using Scala.js With NPM And Browserify
Today, writing applications in languages that compile to JavaScript is a very common practice. Scala developers, for example, can use Scala.js and have the same language for both the server and the client. That said, Scala’s compiler and standard dependency management tools are too limiting in the modern JavaScript world.
In this article, Toptal Freelance Software Engineer Michele Sciabarra shows us how to integrate Scala.js with the plethora of JavaScript modules available on NPM, using tools like Browserify, and explains how to do this without even having to install Node.js.
