let data = [0, 3, 4, 7, 7, 9];
ArrayExt.slice(data);                         // [0, 3, 4, 7, 7, 9]
ArrayExt.slice(data, { start: 2 });           // [4, 7, 7, 9]
ArrayExt.slice(data, { start: 0, stop: 4 });  // [0, 3, 4, 7]
ArrayExt.slice(data, { step: 2 });            // [0, 4, 7]
ArrayExt.slice(data, { step: -1 });           // [9, 7, 7, 4, 3, 0]
