The example would be (where the \'if\' statemen

Answer 1

You could use .test() which returns a boolean value when is find what your looking for in another string:

var thisExpressions = [ '/something/', '/something_else/', '/and_something_else/'];
var thisString = new RegExp('\\b' + 'else' + '\\b', 'i');
var FoundIt = thisString.test(thisExpressions);  
if (FoundIt) { /* DO STUFF */ }

Answer 2

Consider breaking this problem up into two pieces:

1. filter out the items that match the given regular expression
2. determine if that filtered list has 0 matches in it

const sampleStringData = ["frog", "pig", "tiger"];

const matches = sampleStringData.filter((animal) => /any.regex.here/.test(animal));

if (matches.length === 0) {
  console.log("No matches");
}
