Rule proposal: `prefer-array-some`

Fail

if (array.find(element => element === '🦄')) {
}

const foo = array.find(element => element === '🦄') ? bar : baz;

Pass

if (array.some(element => element === '🦄')) {
}

const foo = array.some(element => element === '🦄') ? bar : baz;

Just experienced one few days ago, and kind of follow up for https://github.com/sindresorhus/eslint-plugin-unicorn/issues/730

Maybe I’ve expressed myself badly but the “hard” part is remembering to return a truthy value in the callback.

One distinct advantage for-of has over array methods is that it works on all iterables (NodeList, Set, Map), so it’s a win-win to use it over array methods.

My issue with array#some and array#every is that I think it’s hard to read/understand. I prefer for-of with a break statement because I don’t have to think about whether the iterator needs to return true or false to break the loop.
