*
* 0. There is a number of ways to manipulate strings in Javascript! To help
* show you a few I'll be showing examples of functions I've made that showcase 
* string manipulation. One thing to note is that strings can be treated like an 
* for the purpose bracket notation and using the property .length.
* Concatenation is another useful way to manipulate strings.
* By using the addition operator you can combine/concatenate strings.
