Variables

A variable is a label for storing a value so you can retrieve it later. In Junlang, you don't give variables names — instead, variables are distinguished by the number of ! characters.

What is a variable?

A variable is a name attached to a value. For example, if you compute 1 + 2 and store the result somewhere, you don't have to recompute it every time you need it later. A variable is the box that holds that value.

Most languages give variables names like x, name, or total, but Junlang doesn't.

Variable Names

In Junlang, a variable's name is determined by the count of ! characters.

Junlang	Meaning
!	Variable 1
!!	Variable 2
!!!	Variable 3
!!!!	Variable 4

The more ! characters, the different the variable. In other words, ! and !! are completely separate variables.

Variable Reference

To retrieve a stored value, simply use the variable name in an expression.

오준서!ㅋ

Outputs the value of variable 1 (!).

오~준서!ㅋ

An expression that adds 1 to the value of variable 1. If variable 1 holds 2, the result of this expression is 3.

TIP

How to output a variable's value is covered in Input / Output.
How to store a value in a variable (assignment) is covered in Expressions and Operators - Assignment Operator.

Undefined Variables

Referencing a variable that has never been assigned a value produces the following error:

그 준서는 누구야?

Therefore, you must assign a value to a variable before using it.

오~준서!ㅋ
오준서!ㅋ

This code first assigns 오(1) to variable 1, then outputs its value. The result is 오(1).

The dual role of !

! serves as both a variable name and a logical NOT operator. The interpreter distinguishes between the two based on context.

Code	Interpretation
!오	not 1 (negation operator)
!~오	variable 1 + 1 (variable name)
