Changing Cases of String Variables

In JavaScript, we can convert lower-case string values to upper-case and vice versa. To convert lower-case string to upper-case we use the method toUpperCase() while the method toLowerCase() is for converting string into lower-case. Let’s look at an example.

The titles of the books are usually written in upper-case. In the code below, a variable named bookTitle with the value Think and grow rich has been given to you. Your task is to display the value of the above variable in the upper-case.
