Script Preparation code:

const dirtySet = (new Set()).add(0).add(2);

function checkDirtyNumber(bits, offset) {
    return dirtyNumber & (bits << offset);
}

function checkDirtyBigInt(bits, offset) {
    return dirtyBigInt & (BigInt(bits) << BigInt(offset));
}

function checkDirtySet(index, offset) {
    return dirtySet.has(index + offset);
}

var base = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20];
var staged = Object.create(base);

staged[10] = 110;
staged[12] = 112;
staged[15] = 115;

function checkDirtyProto(ctx, index) {
  return ctx.hasOwnProperty(index); 
}

const hasOwnProperty = Object.prototype.hasOwnProperty;
