Is it possible in JavaScript to do something like preg_match does in PHP ?

I would like to be able to get two numbers from string:

var text = 'price[5][68]';

into two separated variables:

var productId = 5;
var shopId    = 68;

Edit: I also use MooTools if it would help.

get matched string back or false

function preg_match (regex, str) {
  if (new RegExp(regex).test(str)){
    return regex.exec(str);
  }
  return false;
}

Sample code to get image links within HTML content. Like preg_match_all in PHP

let HTML = '<div class="imageset"><table><tbody><tr><td width="50%"><img src="htt ps://domain.com/uploads/monthly_2019_11/7/1.png.jpg" class="fr-fic fr-dii"></td><td width="50%"><img src="htt ps://domain.com/uploads/monthly_2019_11/7/9.png.jpg" class="fr-fic fr-dii"></td></tr></tbody></table></div>';
let re = /<img src="(.*?)"/gi;
let result = HTML.match(re);

out array

0: "<img src="htt ps://domain.com/uploads/monthly_2019_11/7/1.png.jpg""
1: "<img src="htt ps://domain.com/uploads/monthly_2019_11/7/9.png.jpg""

Some Googling brought me to this :

function preg_match (regex, str) {
  return (new RegExp(regex).test(str))
}
console.log(preg_match("^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\\.[a-zA-Z]{2,6}$","test"))
console.log(preg_match("^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\\.[a-zA-Z]{2,6}$","what@google.com"))
