RegEx to extract all matches from string using RegExp.exec

Question

I\'m trying to parse the following kind of string:

[key:\"val\" key2:\"val2\"]

where there are arbitrary key:\"val\" pairs inside. I want t

Iterables are nicer:

const matches = (text, pattern) => ({
  [Symbol.iterator]: function * () {
    const clone = new RegExp(pattern.source, pattern.flags);
    let match = null;
    do {
      match = clone.exec(text);
      if (match) {
        yield match;
      }
    } while (match);
  }
});

Usage in a loop:

for (const match of matches('abcdefabcdef', /ab/g)) {
  console.log(match);
}

Or if you want an array:

[ ...matches('abcdefabcdef', /ab/g) ]
