Object.keys()
, Array.prototype.filter()
and Array.prototype.includes()
to remove the provided keys.Array.prototype.reduce()
to convert the filtered keys back to an object with the corresponding key-value pairs.const omit = (obj, arr) => Object.keys(obj) .filter(k => !arr.includes(k)) .reduce((acc, key) => ((acc[key] = obj[key]), acc), {});
omit({ a: 1, b: '2', c: 3 }, ['b']); // { 'a': 1, 'c': 3 }
