Go Variable Naming Rules

A variable can have a short name (like x and y) or a more descriptive name (age, price, carname, etc.)

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:

Each word, except the first, starts with a capital letter:

myVariableName = "John"

Each word starts with a capital letter:

MyVariableName = "John"

Each word is separated by an underscore character:

my_variable_name = "John"
