Split a string based on substring delimiter, keeping the delimiter in the result

I'd like to be able to split up a string based on a substring delimiter, starting the split before the first character of the delimiter substring. Currently:

var string = "choc: 123 choc: 328 choc: 129";
string.split("choc");

Will give me ["", ":123 ", ": 328", ": 129"], but I am looking to get ["choc: 123 ", "choc: 328", "choc: 129"], instead.

You can do it with a positive lookahead as @Nina Scholz said, and add \s* before the lookahead to remove any leading space before choc:

const string = 'choc: 123 choc: 328 choc: 129';
const result = string.split(/\s*(?=choc)/);

console.log(result);

You could take a positive lookahead.

var string = "choc: 123 choc: 328 choc: 129";
console.log(string.split(/(?=choc)/));
