JavaScript Regex Global Match Groups

I\'m sure the answer to my question is out there, but I couldn\'t find the words to express it suc

Answer 1

String.prototype.matchAll is now well supported in modern browsers as well as Node.js. This can be used like so:

const matches = Array.from(myString.matchAll(/myRegEx/g)).map(match => match[1]);

Note that the passed RegExp must have the global flag or an error will be thrown.

Conveniently, this does not throw an error when no matches are found as .matchAll always returns an iterator (vs .match() returning null).

For this specific example:

var input = "'Warehouse','Local Release','Local Release DA'";
var regex = /'(.*?)'/g;

var matches = Array.from(input.matchAll(regex)).map(match => match[1]);
// [ "Warehouse", "Local Release", "Local Release DA" ]
