Rule proposal: prefer-iterator-to-array

[fisker]

Description

Iterator#toArray() is more clear to me that coverts iterator to array than [...iterator], especially when iterator is a long expression.

Examples

// ❌
[...map.values()].map(value => value * 2)

// ✅
map.values().toArray().map(value => value * 2)
map.values().map(value => value * 2).toArray()

Proposed rule name

prefer-iterator-to-array
