# ESLint 

ESLint as a code quality tool is a tool that checks your code for errors and helps you to fix them and enforces a coding style. 


## Setup


1. Install the [ESLint extension](https://eslint.org/docs/latest/user-guide/integrations) for your code editor.
2. Set your editor's default formatter to `ESLint`.

:::tip
For VSCode users, you can set the formatter to `ESLint` in the [**settings.json**](https://code.visualstudio.com/docs/getstarted/settings#_settingsjson).
