How to remove part of string that is in parentheses?-CodePudding

I have a string from which I want to remove the last parentheses "(bob)". So far I use this code to return the value within these parentheses:

const str = "Hello my name is (john) (doe) (bob)";
const result = str.split('(').pop().split(')')[0];
console.log(result);

How would I be able to return the string without these last parentheses?

Possibly not the cleanest solution, but if you always want to remove the text behind last parentheses, it will work.

   var str = "Hello my name is (john) (doe) (bob)";
   var lastIndex = str.lastIndexOf("(");

   str = str.substring(0, lastIndex);
   console.log(str);

You can match the last occurrence of the parentthesis, and replace with capture group 1 that contains all that comea before it:

^(.*)\([^()]*\)

const str = 'Hello my name is (john) (doe) (bob)';
const lastIdxS = str.lastIndexOf('(');

console.log(str.slice(0, lastIdxS).trim());
