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.

For website developers

Most other guides on how to enable JavaScript are outdated, taking no notice of big web browser releases such as Brave and Microsoft Edge. This is why I created this guide.
