How to find a substring in another string in JavaScript?

Can anyone tell me how to find a substring within another string in JavaScript? 


My string is: "The language we use today is JavaScript".  
How do I determine whether this string contains "today"?

Thank you.

This should do it.

        var testString = "The language we use today is JavaScript";

        function doesStringExist(input, token) {
            return input.indexOf(token) > 0;

        alert(doesStringExist(testString, "today"));
