Thanks for raising this issue @fnurl!

I think this may be happening because in the p5.js is currently setup, p5 variable and function names are not available outside setup(), draw(), mousePressed(), etc. So when declaring variables before setup(), you will need to assign them values inside setup() if you wish to use p5 functions. So I think something like this will work:

let x;

function setup() {
     createCanvas(400, 400);
     x = cos(0);
}

function draw() {
     background(220);
}

More information can be found in this section of the p5.js wiki overview!

I am noticing though that the hinter gives much more contextual information about this in the console when using p5.js version 1.x, whereas just the error is returned for p5.js 2.x.
