how to get dynamic substring in javascript?
I have a scroll animation and want to get the transition value to a given time.
const transform = document.getElementsByClassName('slideContainer')[0].style.transform;
For example I get the following value: translate(-2.51028%, 0%) translate3d(0px, 0px, 0px)
But I just want the -2.51028%
How do I do that?

You could use String.prototype.split():
let str = "translate(-2.51028%, 0%) translate3d(0px, 0px, 0px)"
console.log(str.split("(")[1].split(",")[0]);answered Nov 16 '18 at 9:16

Sounds like you might want to use a regular expression - they're great tools for matching patterns in strings. You can match the start of the string, followed by translate(, then capture as many non-comma characters as you can in a group. That group will have the substring you want:
const transform = 'translate(-2.51028%, 0%) translate3d(0px, 0px, 0px)';
const match = transform.match(/translate(([^,]+)/);
// match[0] refers to the entire matched substring,
// match[1] will contain the first captured group:
console.log(match[1]);answered Nov 16 '18 at 9:16

So many people just hate regexes :). I wish I was better at it though...
