Create a named group in a JavaScript RegExp

To create a named group in a JavaScript RegExp, we can use the (?<name>...) syntax:

const text = 'foo bar foo'
const regex = /(?<wanted>bar)/
const result = regex.exec(text)
if (result === null) {
throw new Error('No match')
const wantedGroup = result.groups?.wanted
const wantedGroup: string | undefined
