JavaScript: How to get string between brackets

Question

I want to be able to get a string in between a bracket opened ( and a bracket closed ).

myString = "MT Mokwa (40,000)"

How can I get 40,000 from the string?

Use a regular expression. Or even just `indexOf` and `substring` — Matt Burland, Jun 06 '17 at 20:24

Both of these examples assume that the string will always have a set of parenthesis, opening before closing.

I suggest using substring and indexOf for this:

var result = myString.substring( myString.indexOf( '(' ) + 1, myString.indexOf( ')' ) );

You can also use a regex if you prefer:

var result = /\(([^)]*)\)/.exec(myString)[1];
