Naming Conventions

            

        

          
What is camelCase?

          
The first word starts with a lowercase letter, and subsequent words start with an uppercase letter, like myVariableName.

        

      
        

          
What is snake_case?

          
Words are connected by underscores, and all letters are lowercase, like my_variable_name.
