RegExp source — empty pattern

📖 Usage Example

const re = /hello world/i
console.log(re.source) // → 'hello world'

Read RegExp.source to get the pattern text of the regular expression without slashes or flags.

RegExp.prototype.source

An empty RegExp /(?:)/ has a source of '(?:)' to avoid ambiguity with comments.

Challenge: Verify that /(?:)/.source equals '(?:)'.
