concerning
['x', 'y'].indexOf(mode) !== -1 creating a dynamic array of strings just for index checking might be slow.
Could we create a constant e.g.
var XY = ['x', 'y'];at the upper scope and reuse that here?

or even var XY = {x: 1, y: 1} -> if(XY[mode]) 😅

I don't think we can make that a TODO just yet - perhaps if & when we convert the whole syntax to ES6 we can make sure we include polyfills for this and other feature, THEN we can use it whenever we wish...
