How are multi-dimensional arrays formatted in memory?
...eter, bad things are going to happen. Here's a quick example:

What is the fastest or most elegant way to compute a set difference using Javascript arrays?

B = [1, 3, 4, 7];
diff = A.filter(function(x) { return B.indexOf(x) < 0 })

B = [1, 3, 4, 7];
diff = A.filter(x => !B.includes(x) );
console.log(diff);
