# obj-key-count [![Support me on Patreon][badge_patreon]][patreon] [![Buy me a book][badge_amazon]][amazon] [![PayPal][badge_paypal_donate]][paypal-donations] [](https://github.com/IonicaBizau/ama) [](https://www.npmjs.com/package/obj-key-count) [](https://www.npmjs.com/package/obj-key-count) [](https://www.codementor.io/@johnnyb?utm_source=github&utm_medium=button&utm_term=johnnyb&utm_campaign=github) > 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. :rocket: ## :cloud: Installation ```sh # Using npm npm install --save obj-key-count # Using yarn yarn add obj-key-count ``` ## :clipboard: Example ```js 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 ``` ## :question: Get Help There are few ways to get help: 1. Please [post questions on Stack Overflow](https://stackoverflow.com/questions/ask). You can open issues with questions, as long you add a link to your Stack Overflow question. 2. For bug reports and feature requests, open issues. :bug: 3. For direct and quick help, you can [use Codementor](https://www.codementor.io/johnnyb). :rocket: ## :memo: Documentation ### `objKeysCount(obj, count, sendKey)` Checks if the provided object contains a specifc number of keys. #### Params - **Object** `obj`: The input object. - **Number** `count`: The expected number of object keys. - **Boolean** `sendKey`: If `true`, the key will be returned as value. Use this when you want to check for one key and you want to use the key name. #### Return - **Boolean** `true` if the object has the specified number of keys, `false` otherwise. ## :yum: How to contribute Have an idea? Found a bug? See [how to contribute][contributing]. ## :sparkling_heart: Support my projects I open-source almost everything I can, and I try to reply to 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 :rocket: - [![Buy me a book][badge_amazon]][amazon]—I love books! I will remember you after years if you buy me one. :grin: :book: - [![PayPal][badge_paypal]][paypal-donations]—You can make one-time donations via PayPal. I'll probably buy a ~~coffee~~ tea. :tea: - [![Support me on Patreon][badge_patreon]][patreon]—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`  Thanks! :heart: ## :dizzy: Where is this library used?
