Variables & Scope

Variables store values. Djazair is dynamically typed, meaning variables can hold any type of value and change types over time.

Declaration

Declare variables using let:

let username = "Riyadh"
let age = 30
let balance = 200.50

# Reassignment
balance = 450.75

Scoping Rules

Djazair uses lexical block scoping. Variables declared inside a block (such as an if block, loop, or function body) are local to that block and cannot be accessed outside of it:

let x = 10
if x > 5
    let y = 20 # local to this if-block
    print(x + y) # => 30
end

# print(y) # Error: y is not defined!
