ID: javascript-code-style/max-params

Language: JavaScript

Severity: Notice

Category: Code Style

Description

Having too many parameters can make your code hard to read. The parameters must be used in appropriate order. Forgetting the order of parameters can cause mistakes.

Too many parameters is a code smell. You should refactor your code in smaller reusable bits. While it may be valid to require more than four parameters, you should use object destructuring.

Arguments

max-params: Maximum number of parameters. Default: 4.

Non-Compliant Code Examples

function test(a, b, c, d, e) {}
var test = function(a, b, c, d, e, f) {};
var test = (a, b, c, d, e) => {};
(function(a, b, c, d, e) {});

// object property options
function test(a, b, c, d, e) {}

Compliant Code Examples

function test(d, e, f) {}
var test = function(a, b, c) {};
var test = (a, b, c) => {};
var test = function test(a, b, c) {};

// object property options
var test = function(a, b, c) {};
