How can I implement Ruby's Array.include? in JavaScript?

Question

I have an array tempArray = ["Kathmandu","Pokhara","Dharan"]. To make sure that "Pokhara" is in tempArry, I have to use loop and check every element of tempArray.

Is there a way to implement Ruby's Array.include? so that I don't need to use a loop?

Answer 1

You can use Array.indexOf to search for a value:

var includePokhara = ( tempArray.indexOf("Pokhara") >= 0 );

Unfortunately, Array.indexOf is not implemented in Internet Explorer, but you can look on StackOverflow how to add it back.

Yes, you are right. It is "indexOf". Thanks for additional info related to IE. – Adventurism

EDIT - in es6 you can just use includes:
'Blue Whale'.includes('blue'); // returns false

You can also use jQuery for that, which has more elegant way to write it:

$.inArray(value, array)
