eslint-plugin-no-param-reassign-allow-reduce

eslint-plugin-no-param-reassign-allow-reduce

The rule no-param-reassign is a worthwhile rule to enable but array.reduce requires you to break this rule. Use this rule instead which allows you to enable the rule but does not throw errors when you do this within the contex of the array.reduce function.

Installation

You'll first need to install ESLint:

$ npm i eslint --save-dev

Next, install eslint-plugin-no-param-reassign-allow-reduce:

$ npm install eslint-plugin-no-param-reassign-allow-reduce --save-dev

Note: If you installed ESLint globally (using the -g flag) then you must also install eslint-plugin-no-param-reassign-allow-reduce globally.

Usage

Add no-param-reassign-allow-reduce to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

{
    "plugins": [
        "no-param-reassign-allow-reduce"
    ]
}

Then configure the rules you want to use under the rules section.

{
    "rules": {
        "no-param-reassign-allow-reduce/allow-reduce": 2,
        "no-param-reassign-allow-reduce/no-reduce-identifiers": 2
    }
}
