What is the fastest or most elegant way to compute a set difference using Javascript arrays?
...'t know if this is most effective, but perhaps the shortest
A = [1, 2, 3, 4];
B = [1, 3, 4, 7];
diff = A.filter(function(x) { return B.indexOf(x) < 0 })
console.log(diff);
Updated to ES6:
A = [1, 2, 3, 4];
B = [1, 3, 4, 7];
diff = A.filter(x => !B.includes(x) );
console.log(diff);
