No bloat. No dependencies.** **Common Utilities** is an ecosystem of simple utility JavaScript functions for everyday development. ### Hello! 🙌 **This project is built to provide JavaScript utility functions that are:** * Easy to use 😌 * Simple 👌 * Tested ✅ * Typed (using Typescript) 📝 * Example containing 📚 * Collaborative 🎳 Just because this repository is currently under [**@yowainwright**](https://github.com/yowainwright) on Github. It can be moved to a **Github org** if others get involved! Please give **Common Utilities** a [**star on Github**](https://github.com/yowainwright/common-utilities), share, or give feedback if the documentation or packages themselves help you or need improvement! ### Why? 🤔 Often engineers write simple functions to do simple things. There is always an option to reach for a heavier tool to do something like a **deep merge**. However, often engineers can do something **simple** to satisfy their use-case. \ \ **Common Utilities** aims to provide functions for the **simple** use-case described above but with **types** and **tests**. This means engineers can use a smaller function from Common Utilities that looks much like something they would write quickly but not need to write tests or types because Common Utilities provides those things. Inversely, using a utility function from Common Utilities adds very little extra bloat for each utility used. ### Common Utilities 🧰 **No cruft. No bloat. No dependencies.** Simple, typed, functional, documented, and tested javascript utility functions.

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://yowainwright.gitbook.io/common-utilities/master.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
