Rule proposal: prefer-array-from
Description
Often no-for-loop results in something that be simplified down to Array.from
Note for even simpler cases are handled by #1713
This is an alternative to #1712 and only one of these rules should be implemented. This can been seen as superior to #1712 as it works for both arrays and iterators.
Original idea: #1712 (comment)
Fail
const result = []
for (const element of array) {
result.push(transform(element))
}const result = []
for (const [index, element] of array.entries()) {
result[index] = transform(element)
}const result = []
for (const [index, element] of array.entries()) {
result.push(anotherArray[index](element))
}Pass
const result = Array.from(array, (element) => transform(element))const result = Array.from(array, (element, index) => anotherArray[index](element))
