omit({a: 'a', b: 'b', c: 'c'}, ['a', 'c'])

Filter function

An optional filter function may be passed as the last argument, with or without keys passed on the arguments:

filter on keys

var res = omit({a: 'a', b: 'b', c: 'c'}, function (val, key) {
  return key === 'a';
});
//=> {a: 'a'}

filter on values

var fn = function() {};
var obj = {a: 'a', b: 'b', c: fn};

var res = omit(obj, ['a'], function (val, key) {
  return typeof val !== 'function';
});
//=> {b: 'b'}
