FAQs


What's JavaScript?

JavaScript is a very common programming language used to build interactive websites. It usually runs behind-the-scenes to display dynamic content or provide interactive features. Most browsers have JavaScript enabled by default because of how widely used it is.


Is JavaScript dangerous?

No, JavaScript is almost never dangerous. Malicious sites can run bad code in the background to track and collect data on you, but modern browsers and tracking blockers can keep you safe while still permitting JavaScript. Sites should not be able to access local files, GPS location, camera, or microphone through JavaScript unless you give permission through your browser.


Do I have to enable JavaScript?

It's highly recomended. You technically dont have to enable JavaScript if you don't want to. However, almost everything on the web nowadays is script-dependent and needs JavaScript in some way. For example, you won't be able to perform a Google search with JavaScript disabled. To enable JavaScript on your browser, follow the steps above. Back to Top.
