string.toUpperCase()

Returns

The uppercase (a.k.a. ALL CAPS) equivalent of string as a new string. Characters without an uppercase equivalent are left unchanged.

Description

The toUpperCase( ) method creates a new, uppercase version of string; it can be used for formatting or for facilitating case-insensitive character comparisons.

Usage

Note that toUpperCase( ) does not modify string; it returns a completely new string.

Example

"listen to me".toUpperCase();   // Yields the string "LISTEN TO ME"
var msg1 = "Your Final Score: 234";
var msg2 = msg1.toUpperCase();  // Set msg2 to "YOUR FINAL SCORE: 234"
