RegExp exec() — capture group

📖 Usage Example

const re = /(\d+)/
const match = re.exec('Price: 42')
console.log(match[0]) // → '42'
console.log(match[1]) // → '42'

Use RegExp.exec() to search for a match and return detailed match information.

RegExp.prototype.exec()

Capture groups are returned in the result array starting at index 1.

Challenge: Verify that /(\d+)/.exec('abc123')[1] equals '123'.
