Lesson 08 — Arrays

Syntax

const arr be [1, 2, 3]      -- array literal
const x be arr[\0]          -- index access (note the \)
const nums be [0..4]        -- range: [0, 1, 2, 3, 4]
const [a; b] be arr         -- destructuring

Since [] is also used for function calls, index access needs a \ prefix:

Task

1. Get the first element of numbers into first.

2. Build [0, 1, 2, 3, 4] with a range literal.

3. Replace the two const ... be //;???;// lines with one destructuring line.
