 # Guidelines
-* Modules must not depend on any other npm modules (inlcuding other just modules)
+* Modules must not depend on any other npm modules (including other just modules)
 * Always assume Just modules will be used in hot code and code accordingly
   * Write in ES5
   * Favor `for` loops over high order functions
   * Don't repeatedly access the same property, assign it to a `var`
 * Brevity
   * A lot of people choose Just utilities to minimize their app's JS footprint in memory/network constrained environments
-  * Keep it brief and don't add redundant code. Most utilites should fit into one shortish function.

 * API

   * Avoid multiple arguments or option arguments whenever possible–-make it just do one thing
 * Tests
   * Write a test for each use case

   * Please add these files for your new utility if you feel comfortable doing so. [Here's](https://github.com/angus-c/just/pull/247/files) an example PR.
   * Also add `"types": "index.d.ts"` after `main` entry in package.json. 
   * You can verify new TypeScript definitions by running `yarn test-types` (This also gets run as part of the `yarn test` script)

 # README template
 * Thanks to [Max Synnott](https://github.com/maxsynnott), local and global READMEs are now autogenerated from a template.
 * Add a new section to [md-variables.com](https://github.com/angus-c/just/blob/master/md-variables.json) for your package:
-  *  root key: the `name` value from your `package.json` (e.g. `just-comapct`)
+  *  root key: the `name` value from your `package.json` (e.g. `just-compact`)
   *  `packageName`: same as root key
   *  `dir`: the directory you wrote your package in (e.g. `array-compact`)
   *  `description`: a one sentence description of what the utility does (for line breaks use an array of strings)
