Regex match indices

Regex match has been upgraded to include more information about the matching groups. The additional information includes starting and ending indices of matches in a RegExp with the usage of \d flag in the input string.

Let's take an example of regex pattern on the input string without \d flag and the information of the matches.

const regexPatter = /Jack/g;
const input = 'Authos: Jack, Alexander and Jacky';
const result = [...input.matchAll(regexPatter)];
console.log(result[0]); // ['Jack', index: 8, input: 'Authos: Jack, Alex and Jacky', groups: undefined]

Whereas \d flag provides an additional array with the indices of the different elements that match the regex,

const regexPatter = /(Jack)/gd;
const input = 'Authos: Jack, Alexander and Jacky';
const result = [...input.matchAll(regexPatter)];
console.log(result[0]); // ['Jack', 'Jack', index: 8, input: 'Authos: Jack, Alexander and Jacky', groups: undefined, indices: Array(2)]

ES2023 Or ES14

ECMAScript 2023 or ES14 has been released in the month of June 2023 with some of important features like adding new methods for searching and altering the arrays, supporting symbols as keys for WeakMap API and standardizing the hashbang syntax in JavaScript.
