描述

Description

This rule would enforce users to simplify negations: !(a === b) -> a !== b. There might be other conditions like this that could be simplified.

Fail

if (!(a > b)) {}
const foo = !(bar === baz);
const foo = !(typeof bar === 'undefined');

Pass

if (a <= b) {}
const foo = bar !== baz;
const foo = typeof bar !== 'undefined';
const foo = !Array.isArray(bar);
