Converting Processing to Processing.js... please help?

[ARNAV_A_GUPTA]

I think this would be correct. Try this.

@Quinny

function preload() {
    loadImage("img.jpg", function(_img) {
    img = _img;
    img.loadPixels();
    loaded = true;
    segmentSpacing = (img.height / numSegments);
    segmentLength = img.width;

    for (let i = 0; i < numSegments; i++) {
      segments.push(new Segment({
        pos: { x: 0, y: i },
        len: segmentLength
      })
)
};

    }
};
