You can’t get very far in tech without running smack into JavaScript. Chances are, you’re right here, right now because you’ve heard the term and know you need to understand it. The good news is: JavaScript isn’t as scary as it sounds—and yes, you can learn how to use it.
JavaScript: A Quick Definition
JavaScript is a scripting language used to create and control dynamic website content, i.e. anything that moves, refreshes, or otherwise changes on your screen without requiring you to manually reload a web page. Features like:
- animated graphics
- photo slideshows
- autocomplete text suggestions
- interactive forms
An even better way of understanding what JavaScript does is to think about certain web features you use every day and likely take for granted—like when your Facebook timeline automatically updates on your screen or Google suggests search terms based on a few letters you’ve started typing. In both cases, that’s JavaScript in action.
The results of JavaScript may seem simple, but there’s a reason why we teach an entire segment on JavaScript in both our Front End Web Developer and Break into Tech Blueprints. Underneath all those great animations and autocompletes—there’s some pretty fascinating stuff happening. This guide will break down exactly how JavaScript works and why and how to use it, plus the best ways to learn JavaScript if you’re realizing you need it in your skillset.
