Learn how to turn on JavaScript in your web browser

The majority of websites nowadays rely on JavaScript. JavaScript is a programming language that is regularly used to make websites more functional and improve the overall user experience for a website's users. When JavaScript is disabled, the majority of modern websites simply become unusable or do not work as intended as they require the usage of JavaScript to function properly.
