String.prototype.match() — global flag returns all matches

📖 Usage Example

'test 123 foo'.match(/d+/)    // → ['123', index: 5, ...]
'test 1 and 2'.match(/d+/g)  // → ['1', '2']

Use match() to search a string against a regex and return the match results, or null if not found.

String.prototype.match() — Global Flag

With the g flag, .match() returns an array of all matched strings (no capture group details).

Challenge: Implement allWords(str) that returns all word tokens using /\w+/g.

allWords('hello world foo') // → ['hello', 'world', 'foo']
