Bezier Curve in Javascript (es6)

// takes [x, y] array objects for the points
function bezier(t, p0, p1, p2) {
    const ay = Math.pow(1 - t, 2) * p0[1];
    const by = 2 * (1 - t) * t * p1[1];
    const cy = Math.pow(t, 2) * p2[1];

    const ax = Math.pow(1 - t, 2) * p0[0];
    const bx = 2 * (1 - t) * t * p1[0];
    const cx = Math.pow(t, 2) * p2[0];

    const y = ay + by + cy;
    const x = ax + bx + cx;

    return [x, y];
};

function bezierCurve(p0, p1, p2, intervalSize) {
    const curve = [];

    for(let i = 0; i < 1; i = i + intervalSize) {
        curve.push(bezier(i, p0, p1, p2));
    }

    return curve;
