toUpperCase() is not making the string upper case

Question

I don\'t know what I\'m doing wrong; But somehow .toUpperCase() String-function is not working on my browser or do I get something wrong?

var string          


        

Answer 1

.toUpperCase returns the upper-cased string. It is not an in-place modifier method.

string = string.toUpperCase();
