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;
