Rules for Variable's Names

 

 Six rules you must always consider and follow each time you declare a variable name.

 1. A variable name must start with a letter or an underscore character (_)

 2. A variable name cannot start with a digit

 3. A variable name can only contain alpha-numeric characters and underscores (a-z, A-Z, 0-9, and _ )

 4. Variable names are case-sensitive (age, Age, and AGE are three different variables)

 5. There is no limit on the length of the variable name

 6. A variable name cannot contain spaces

 7. The variable name cannot be any Go keywords

Multi-Word Variable Names:

1. Camel Case: Each word, except the first, starts with a capital letter

                    Syntex: myVariableName = "John"

2. Pascal Case: Each word starts with a capital letter

                     Syntex: MyVariableName = "John"

3. Snake Case: Each word is separated by an underscore character

                     Syntex: my_variable_name = "John"
