/*In JavaScript, String values are immutable, which means that they cannot be altered once created.
For example, the following code:*/
var myStr = "Bob";
myStr[0] = "J";
// cannot change the value of myStr to "Job", because the contents of myStr cannot be altered.
// Note that this does not mean that myStr cannot be changed, just that the individual characters
// of a string literal cannot be changed. The only way to change myStr would be to assign it with a
// new string, like this:
var myStr = "Bob";
myStr = "Job";
