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

Here's a one line solution without a while loop.

The order is preserved in the resulting list.

The potential downsides are

1. It clones the regex for every match.
2. The result is in a different form than expected solutions. You'll need to process them one more time.

let re = /\s*([^[:]+):\"([^"]+)"/g
let str = '[description:"aoeu" uuid:"123sth"]'

(str.match(re) || []).map(e => RegExp(re.source, re.flags).exec(e))

[ [ 'description:"aoeu"',
    'description',
    'aoeu',
    index: 0,
    input: 'description:"aoeu"',
    groups: undefined ],
  [ ' uuid:"123sth"',
    'uuid',
    '123sth',
    index: 0,
    input: ' uuid:"123sth"',
    groups: undefined ] ]
