(back to top) What Do JavaScript Jobs Look Like?Īccording to Elaine Queathem, Founder at coding bootcamp Savvy Coders, some of the most common JavaScript jobs include front end web development (building the user-facing, visual parts of a website), web application development (creating web-based software applications including interactive online forms and shopping carts, word processing and spreadsheet programs, video and photo editors, file conversion and scanning programs, and email software), and website administration (maintaining, backing up, and updated existing websites for an organization). According to Cho, the strong presence of JavaScript jobs in the workforce can be attributed to two things-the foundational nature of the language (as of this writing, JavaScript helps provide the foundation for 95.1% of all active websites) and the robust array of features JavaScript brings to those foundations (unlike the relatively cut-and-dried text and formatting of HTML and CSS, JavaScript’s features provide a flexible, added layer that make sites stand out and present as highly functional). These online classes are designed to completed in three months by spending just an hour a day on the materials.Īmy Cho, CTO at diversity hiring site Hirekind, says that about one third of all programming-related jobs listed on sites like Indeed require JavaScript proficiency. We’ll answer that question in this article, and-when you’re ready to start learning the skills to GET this jobs-take a look at our Skillcrush Front End Developer and Web Developer Blueprint Courses. But how exactly do JavaScript skills translate to jobs when it comes to nailing down paid work? Since most websites eventually require content and features above and beyond static text, JavaScript is an important addition to an HTML/CSS foundation.

Where markup languages like HTML and CSS give web browsers instructions on how to display a website (defining static things like headers, fonts, paragraphs, etc.), JavaScript executes the features on a page that need to update in real time without a user having to refresh their screen (things like interactive maps, animated graphics, scrolling video, jukeboxes, etc.). Well, let's take a look at an example of asynchronous code.If you’re not familiar with JavaScript or you need a refresher, it’s a scripting language used to add and control dynamic content on a website. It doesn't want to do all of the work itself, so it farms it out to something else.īut who is this mysterious entity that works for JavaScript? And how does it get hired to work for JavaScript? Who is doing the other work?Īlright, so we know that JavaScript is synchronous and lazy.
Then when it's ready, it will receive the results back from the work. JavaScript is delegating the work to something else, then going about it's own business.

They aren't juggling, so they can go and get the ball for you, then toss it into your juggling at a time when your hand is free and you are ready to add another ball mid-juggle. The solution? Delegate the work to a friend or family member. But you can't go and get another ball either, because that would mean you'd have to stop. You don't want to stop juggling, because it's just so much fun. What would happen if you wanted to add another ball? Instead of six balls, you wanted to juggle seven balls. Let's circle back to the juggling example.

Because it's effectively blocking other code from running. We call this this kind of synchronous code blocking. It's the same with JavaScript: once the code is running, it has its hands full with that code. While you are juggling, your hands are occupied and can't handle anything else. You can think of this as if you were juggling six small balls. The result of this design decision is that only one thing can happen at any one time. This means that when code is executed, JavaScript starts at the top of the file and runs through code line by line, until it is done. What is asynchronous code?īy design, JavaScript is a synchronous programming language. Let's go explore this concept, and learn a lot about JavaScript in the process.Īre you ready? Let's go. Well it turns out that understanding asynchronous functions requires a great deal of knowledge about how JavaScript works fundamentally. When does an asynchronous function finish? And why is this such a hard question to answer?
