Naming Variables in JavaScript

There are a few rules that we must follow to ensure that we don't break our code.

1. There can be no spaces or dashes in our code names.
2. • Names like let first name = ... or let first-name = ... are not viable.
2. Names must begin with a letter of the alphabet -> a-z, A-Z.
3. • Best practice in JS is to start your variables with a lowercase letter e.g. let name = ... as opposed to let Name = ....
3. For multi-word variables, we use either the camelCase or snake_case.
4. • camelCase capitalizes the first letter of each word in a phrase, without using spaces or punctuation (with exception to the first word).
   • snakecase is a way of writing phrases without spaces, where spaces are replaced with underscores ``, and the words are all lower case.

So the correct way to write the first name example above would be:

• let firstName = "Arnob" or let first_name = "Arnob"
