Return all string matching the given pattern regex

Question

Need to return all string matching a regex.

let text = "data.check && Obj[data.check]['display_119']) {  1549: displayName = obj[data.check]['display_12']";

var identifiers = text.match("display_[0-9]+$");

identifiers should be an array containing

["display_119", "display_12"]; //expected

You can omit the $ like var identifiers = text.match(/display_[0-9]+/g); — The fourth bird

To get the expected result, you should transform the string you're passing to match() in a regular expression. Also, as commented, you're not expecting results that are only at the end of text, so you don't need $ in your RegExp.

let text = "data.check && Obj[data.check]['display_119']) {  1549: displayName = obj[data.check]['display_12']";

var identifiers = text.match(/display_[0-9]+/g);

console.log(identifiers)
