Javascript is a high-level programming language primarily used for web development. It allows web pages to be made dynamic and interactive, enabling the creation of dynamic content, control of multimedia, animations, and just about anything .

. Unlike HTML and CSS, which deal with the structure and style of pages respectively, JavaScript allows elements to be manipulated in real time, responding to user input and changing the content of the page without the need to reload it.

In creative coding, JavaScript is used to generate interactive graphics and animations directly in the browser. Visual programming tools such as Cables.gl and p5.js make it accessible even to nonprogrammers.

Thanks to compatibility with libraries such as WebGL, JavaScript allows advanced generative graphics, data visualizations and interactive environments to be created without the need for external software, making it one of the most widely used languages in creative coding.
