toUpperCase() is not making the string upper case
javascript
Solution
`.toUpperCase` returns the upper-cased string. It is not an in-place modifier method.
string = string.toUpperCase();

Problem
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 ="kjsdgfiIJHBVSFIU"; string.toUpperCase(); console.log(string); ``` Live demo
