String.prototype.replaceAll() — regex with g flag

📖 Usage Example

'foo bar foo'.replaceAll('foo', 'baz')  // → 'baz bar baz'
'banana'.replaceAll('a', 'o')           // → 'bonono'

Use replaceAll() to replace every occurrence of a search string or regex (with /g flag) with the replacement.

String.prototype.replaceAll() — Regex with /g

When passing a regex to replaceAll, it must have the g flag.
