Braces and parentheses should be used consistently with arrow functions

Shared coding conventions allow teams to collaborate effectively. This rule raises an issue when the use of parentheses with an arrow function does not conform to the configured requirements.

Noncompliant Code Example

With the configured defaults forbidding parentheses

var foo = (a) => { /* ... */ };  // Noncompliant; remove parens from arg
var bar = (a, b) => { return 0; };  // Noncompliant; remove curly braces from body

Compliant Solution

var foo = a => { /* ... */ };
var bar = (a, b) => 0;
