javascript find string in array fastest

 

 

 

 

As far as Ive read: indexOf is a slow linear search through your entire list to see if it finds the string. So: If you either sort the values in ip so you can use a faster searching algorithm or implement ip as a hashmap you should be able to get improved efficiency. So: Option 1: Sort the array that holds all JavaScript performance comparison. Revision 5 of this test case created by on 2012-1-26. Preparation code.Java applet disabled. Testing in YandexBot 3.0.0 / Other 0.0.0. Test. Ops/sec. As others have said, the iteration through the array is probably the best way, but it has been proven that a decreasing while loop is the fastest way to iterate in JavaScript.check if a string is part of an array - javascript.

Whats the best (i.e. fastest) way to find out if an array contains a given value?I think I understand that, but let me test my understanding: It joins the array into a string, and then searches inside the string for the given value?
