Install

Install with npm:

sh $ npm install --save object.omit

Usage

js var omit = require('object.omit');

Pass a string key to omit:

js omit({a: 'a', b: 'b', c: 'c'}, 'a') //=> { b: 'b', c: 'c' }

Pass an array of keys to omit:

js omit({a: 'a', b: 'b', c: 'c'}, ['a', 'c']) //=> { b: 'b' }

Returns the object if no keys are passed:

js omit({a: 'a', b: 'b', c: 'c'}) //=> {a: 'a', b: 'b', c: 'c'}

Returns an empty object if no value is passed.

js omit() //=> {}

Filter function

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

filter on keys

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

filter on values

```js 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'} ```
