visuco

How visuco works — a 1-minute walkthrough

Every challenge shows a target and asks you to write code that matches it. Let's fix one together — just follow the prompts as they pop up.

Your code example
let x = 0;
function everyFrame() {
backgroundColour(BLACK);
shapeColour();
square(x, 40, );
x = x + 2;
}

Locked code is grey. The green boxes are the only parts you can change.
