prefer-array-find.md

Prefer .find(…) over the first element from .filter(…)

Array#find breaks the loop as soon as it finds a match.

This rule is fixable.

Fail

const item = array.filter(x => x === '🦄')[0];

const item = array.filter(x => x === '🦄').shift();

const [item] = array.filter(x => x === '🦄');

[item] = array.filter(x => x === '🦄');

Pass

const item = array.find(x => x === '🦄');

item = array.find(x => x === '🦄');
