Question:

b' What is the most concise and efficient way to find out if a JavaScript array contains a value?This is the only way I know to do it:function contains(a, obj) { for (var i = 0; i < a.length; i++) { if (a[i] === obj) { return true; } } return false;}Is there a better and more concise way to accomplish this?This is very closely related to Stack Overflow question Best way to find an item in a JavaScript Array? which addresses finding objects in an array using indexOf.
