Description
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
