Variable Naming

Variables must have meaningful names.

Names that relate to the information/data they are storing.

​
A variable that stores the amount someone is paid per hour could be called payPerHour or pay_per_hour.

Meaningful
Variable Names

Camel Casing

This name is given to the naming method where each new word in a variable name is given a capital letter (except the first word!).

payPerHour numberOfSubjects hoursWorked

Like a camel, these variable names have humps!

Snake Casing

This name is given to the naming method where each new word in a variable name is separated by an underscore.

pay_per_hour number_of_subjects hours_worked

These variable names are like 1 long connected line like a snake!
