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

The string object has methods like startsWith, endsWith and includes methods.

• StartsWith checks whether the given string starts at the beginning or not.

• endsWith checks whether the given string is at the end or not.

• includes checks whether the given string is present at any part or not.
