Just before we part our ways keep in mind these below set of rules before naming your variables:
- A variable must not start with a number but can be after succeeding characters of a string.
- No special characters except underscore and dollar are allowed.
- They are obviously case-sensitive.
- As said all the succeeding characters can be alphabets, underscore, and digits.
