How to match multiple words in regex with JavaScript?

To match multiple words in regex with JavaScript, we can use lookahead assertions.

For instance, we write:

const r = /^(?=.*foo)(?=.*bar)(?=.*baz)/
console.log('foobarbazqux'.match(r))
console.log('foobar'.match(r))

to match the substrings containing foo, bar and baz.

The strings in the regex won’t be included in the match.

Therefore, the console logs log

[""]
null
