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

Answer 1

str.match(/regex/g)

returns all matches as an array.

If, for some mysterious reason, you need the additional information comes with exec, as an alternative to previous answers, you could do it with a recursive function instead of a loop as follows (which also looks cooler).

function findMatches(regex, str, matches = []) {
   const res = regex.exec(str)
   res && matches.push(res) && findMatches(regex, str, matches)
   return matches
}

// Usage
const matches = findMatches(/regex/g, str)

as stated in the comments before, it's important to have g at the end of regex definition to move the pointer forward in each execution.
