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

💖 Support my projects

I open-source almost everything I can, and I try to reply everyone needing help using these projects. Obviously, this takes time. You can integrate and use these projects in your applications for free! You can even change the source code and redistribute (even resell it).

However, if you get some profit from this or just want to encourage me to continue creating stuff, there are few ways you can do it:

• Starring and sharing the projects you like 🚀

• —You can make one-time donations via PayPal. I'll probably buy a coffee tea. 🍵

• —Set up a recurring monthly donation and you will get interesting news about what I'm doing (things that I don't share with everyone).

• Bitcoin—You can send me bitcoins at this address (or scanning the code below): 1P9BRsmazNQcuyTxEqveUsnf5CERdq35V6
