Safe browsing
Javascript is a computer programming language commonly used to create interactive effects within web browsers
On this site it is used to load information in the background so you don't have to reload the browser and to simply make the site faster and more responsive
Javascript is an interpreted language so any operation a JavaScript program attempts to perform is restricted by the JavaScript interpreter, this prevents a JavaScript program from doing anything harmfully to your computer
In other words JavaScript is safe but if you want to keep it off, good luck with that
