Go Variable Naming Rules
Go Variable Naming Rules
A variable can have a short name (like x and y) or a more descriptive name (age, price, carname, etc.).
Go variable naming rules:
- A variable name must start with a letter or an underscore character (_)
- A variable name cannot start with a digit
- A variable name can only contain alpha-numeric characters and underscores (
a-z, A-Z,0-9, and_) - Variable names are case-sensitive (age, Age and AGE are three different variables)
- There is no limit on the length of the variable name
- A variable name cannot contain spaces
- The variable name cannot be any Go keywords
Multi-Word Variable Names
Variable names with more than one word can be difficult to read.
There are several techniques you can use to make them more readable:
Camel Case
Each word, except the first, starts with a capital letter:
myVariableName = "John"
Pascal Case
Each word starts with a capital letter:
MyVariableName = "John"
Snake Case
Each word is separated by an underscore character:
my_variable_name = "John"
