JavaScript

JavaScript's versatility makes it a critical language in web design. While early site designers relied almost exclusively on HTML and later CSS for their development, JavaScript's robust functionality can be used to create apps, web pages, and programs with more interactivity for the user. With JavaScript, developers can more effectively integrate games into their content, animate elements within a website, and more easily validate input on online forms. Moreover, the JavaScript code runs directly through the user's browser, speeding up the process at which information is processed and preventing latency issues and slowdown issues on the backend of the design.
