extract

Extract properties from objects and generate a new object.

Installation

npm install extract

Usage

var extract = require('extract');
var sample = {foo: 123, bar: 'baz'};
var result = extract(sample, ['foo'])
 
console.log(result);

Will print {foo: 123}.

Why?

I use this pattern quite a lot in node.js to deal with things such as mass-assignment.
