I have a regex to check if a string contains a specific word. It works as expected:

/bwordb/.test('a long text with the desired word amongst others'); // true

/bamongb/.test('a long text with the desired word amongst others'); // false

But i need the word which is about to be checked in a variable. Using new RegExp does not work properly, it always returns false:

var myString = 'a long text with the desired word amongst others';



var myWord = 'word';

new RegExp('b' + myWord + 'b').test(myString); // false



myWord = among;

new RegExp('b' + myWord + 'b').test(myString); // false

What is wrong here?
