Is there a way in JavaScript to get Boolean value for a match of the string against the array of regular expressions?

The example would be (where the 'if' statement is representing what I'm trying to achieve):

var thisExpressions = [ '/something/', '/something_else/', '/and_something_else/'];
var thisString = 'else';

if (matchInArray(thisString, thisExpressions)) {

}

Using a more functional approach, you can implement the match with a one-liner using an array function:

ECMAScript 6:

const regexList = [/apple/, /pear/];
const text = "banana pear";
const isMatch = regexList.some(rx => rx.test(text));

ECMAScript 5:

var regexList = [/apple/, /pear/];
var text = "banana pear";
var isMatch = regexList.some(function(rx) { return rx.test(text); });
