I have this processing.js code made on khan academy:
background(255, 255, 247);
stroke(173, 222, 237);
for (var i = 0; i < 20; i++) {
var lineY = 20 + (i * 20);
line(0, lineY, 400, lineY);
}
for (var j = 0; j < 20; j++) {
var x = 20 + (j * 20);
line(x, 0, x, 400);
}
What does the
var lineY = 20 + (i * 20);
code do? And what does the
var x = 20 + (j * 20);
code do?
Im a beginner
