Lesson 02 — Variables

日本語

Syntax

Variables must be declared with const, let, or var. Purus uses be instead of =:

const pi be 3.14     -- constant (cannot reassign)
let count be 0       -- mutable variable

To update a mutable variable, use compound assignment:

count add be 10      -- count += 10
count sub be 1       -- count -= 1
count mul be 2       -- count *= 2

Task

1. Make the constant language hold the string Purus.

2. Add 10 to count using add be.
