The 10 Skills You Need to Land Your First Front End Developer Job
2. JavaScript/jQuery
Another MAJOR tool in your front end developer toolbox is going to be JavaScript (JS). Where HTML is a markup language and CSS is a style sheet language, JS is the first language I’ve mentioned that’s a bonafide programming language. What’s the difference? Where HTML and CSS determine the presentation of a page, JS determines the function.

In some instances a very simple website or web page is fine, but for situations where you need interactive features—audio and video, games, scrolling abilities, page animations—JS is the tool you’ll use to implement them (though as CSS evolves, it’s starting to handle a lot of these duties as well).

One cool thing to keep in mind about JS is the existence of libraries like jQuery, a collection of plugins and extensions that make it faster and easier to use JS on your website. jQuery takes common tasks that require multiple lines of JS code and compresses them into a format that can be executed with a single line. This will be a big help when you’re coding with JS. Unless, of course, you don’t like saving time. ;)
