How to check if a string “StartsWith” another string?

Question

How would I write the equivalent of C#\'s String.StartsWith in JavaScript?

var haystack = \'hello world\';
var needle = \'he\';

haystack.startsWith(needle)          


        

Answer 1

I am not sure for javascript but in typescript i did something like

var str = "something";
(str).startsWith("some");

I guess it should work on js too. I hope it helps!
