Replace string which is between two characters

Question

I am having the following string 4 (10.3%) and would like to receive 4.

I tried:

let s = "4 (10.3%)"
s.replace("/\s+\((.*?)\)", "");

console.log(s)

However, I still get the initial string back.

Any suggestion what I am doing wrong?

I appreciate your replies!

Why cant you split the string on the whitespace and take the first part of the array? — Will, May 23 '19 at 09:29
In addition to the duplicate, it looks like you're trying to use a regular expression, in which case you should actually use a regular expression, not a string. — CertainPerformance, May 23 '19 at 09:30
That's looking for the *string* `"/\s+\((.*?)\)"`. Use a regex: `/\s+\((.*?)\)/`. — Jack Bashford, May 23 '19 at 09:30

Use this instead of regex

let s = "4 (10.3%)"
console.log(s.substr(0, s.indexOf(' ')))

Using split

let s = "4 (10.3%)"
    console.log(s.split(" ")[0])
