Keywords in JavaScript
These are special, reserved words used for things like declaring objects and variables, assigning special values ("true," "false," "null") and controlling iterative loops [well, more on that stuff later].
The JS keywords are:
| break | continue | delete | else |
| false | for | function | if |
| in | new | null | return |
| this | true | typeof | var |
| void | while | with |
