::drop()

Return the this object stripped of some properties.

const drop = require('this-drop');
const abc = {a: 1, b: 2, c: 3};

abc::drop(['a', 'c']);
//» {b: 2}

$ npm install this-drop

<pre> object::drop(keys) ⇒ newObject </pre>

keys should be iterable – you’ll probably want to use an array here.

We don’t mutate the object. We make a shallow copy instead:

const xyz = {x: 1, y: '2', z: [3]};
const xz = xyz::drop(['y']);

xyz.z === xz.z;
//» true

Note that the example uses the ES 2016 function bind syntax. You can still use the library in any JS engine down to ES5 though:

drop.call(abc, ['a', 'c']);
//» {b: 2}
