At the moment I am engaged in construction activities, but I have long wanted to change my field.
describe(“Sample tests”, function() {
it(“Should pass Sample tests”, function() {
Test.assertDeepEquals(arrayDiff([], [4,5]), [], “a was [], b was [4,5]”); Test.assertDeepEquals(arrayDiff([3,4], [3]), [4], “a was [3,4], b was [3]”); Test.assertDeepEquals(arrayDiff([1,8,2], []), [1,8,2], “a was [1,8,2], b was []”); Test.assertDeepEquals(arrayDiff([1,2,3], [1,2]), [3], “a was [1,2,3], b was [1,2]”) });
});
#### return a.filter(e => !b.includes(e));
