Variables

Variables in Kexra store values that can be referenced and modified throughout a program.

Why this exists​

Variables allow programs to store and manipulate data, enabling dynamic behavior and reusable computations.

How it works​

Variables are declared using set and can hold any value type. They can be reassigned and their values can change during execution.

Examples​

# Declare a variable
set x 42
say x  # Outputs: 42

# Reassign a variable
set x "hello"
say x  # Outputs: hello

# Use in expressions
set y x + 10  # Error: x is now a string

Common mistakes​

  • Using set without a value (variables must be initialized)
  • Confusing variable names with keywords
