obj-key-count

A fast way to check if the object has a specific number of properties.

This is not using the Object.keys(obj).length method but iterates a part of object until it reaches the specified count. 🚀

☁️ Installation

$ npm i --save obj-key-count

📋 Example

const objKeysCount = require("obj-key-count");

console.log(objKeysCount({}, 0));
// => true

console.log(objKeysCount({ foo: 42}, 1, true));
// => "foo"

console.log(objKeysCount({}, 1));
// => false

console.log(objKeysCount({ foo: 42, bar: "baz" }, 2));
// => true
