What does this mean: => or >=

Question

What is the difference and what do they mean: => , >=,

I seen this => one in animations (DOM) a lot of times

Answer 1

I think you know, >= is a comparison operator that returns true if the first value is bigger than or equal to the second one.

=> is used for "arrow functions". It is a shortcut for inlinefunctions. Syntax:
const(/let) func = () => {
//code
}
If you only have 1 line of code which is a return value, you can exclude the curly brackets and the return keyword:
const twoTimes = x => x * 2;
