Superficial guide to naming variables (JS/TS)

Boolean variables - use a helping verb as a prefix
- Ex. isChecked, isOpen, willToggle
Function names - use a verb as a prefix
- Ex. checkIsValid, submitPost, fetchPost
Keep variable names descriptive enough
Declaring variables
- Use const for declaring by default
- Use let if variable is going to be reassigned
- Never use var
Its okay if variable names are long
