A Non-Technical Guide to Javascript

Javascript is a programming language created specifically for the web.

Where HTML and CSS are both markup languages that help give meaning to specific content on a webpage, Javascript is a formal programming language that allows you to do the dynamic tasks we've come to expect from modern websites.

What does Javascript do?

Javascript is behind everything dynamic behind a webpage. It's hard to tell by just looking at a webpage where Javascript might be used but think of things like:

• A modal dropping down
• Clicking something to reveal information
• Additional content loading on click or scroll
• Tags over an image
• A menu dropping down
• Almost all animations (sliding, bouncing, rotating)
• Filtering information without a page reload
