# :construction: Notice :construction: Pardon the mess. The `master` branch is in flux while we work on Lodash v5. This means things like npm scripts, which we encourage using for contributions, may not be working. Thank you for your patience. # Contributing to Lodash Contributions are always welcome. Before contributing please read the [code of conduct](https://code-of-conduct.openjsf.org) & [search the issue tracker](https://github.com/lodash/lodash/issues); your issue may have already been discussed or fixed in `master`. To contribute, [fork](https://help.github.com/articles/fork-a-repo/) Lodash, commit your changes, & [send a pull request](https://help.github.com/articles/using-pull-requests/). ## Feature Requests Feature requests should be submitted in the [issue tracker](https://github.com/lodash/lodash/issues), with a description of the expected behavior & use case, where they’ll remain closed until sufficient interest, [e.g. :+1: reactions](https://help.github.com/articles/about-discussions-in-issues-and-pull-requests/), has been [shown by the community](https://github.com/lodash/lodash/issues?q=label%3A%22votes+needed%22+sort%3Areactions-%2B1-desc).

Include updated unit tests in the `test` directory as part of your pull request. Unit test files should be named `[filename].test.js`. Before running the unit tests you’ll need to install, `npm i`, [development dependencies](https://docs.npmjs.com/files/package.json#devdependencies). Run unit tests from the command-line via `npm test`. ## Contributor License Agreement Lodash is a member of the [JS Foundation](https://openjsf.org/).

Use two spaces for indentation. No tabs. - **Naming**:
Keep variable & method names concise & descriptive.
Variable names `index`, `array`, & `iteratee` are preferable to `i`, `arr`, & `fn`. - **Quotes**:
Single-quoted strings are preferred to double-quoted strings; however, please use a double-quoted string if the value contains a single-quote character to avoid unnecessary escaping. - **Comments**:
Please use single-line comments to annotate significant additions, & [JSDoc-style](http://www.2ality.com/2011/08/jsdoc-intro.html) comments for functions. Guidelines are enforced using [ESLint](https://www.npmjs.com/package/eslint): ```bash $ npm run style ```
