This method is like `findIndex` except that it iterates over elements of `collection` from right to left.
const users = [
{ 'user': 'barney', 'active': true },
{ 'user': 'fred', 'active': false },
{ 'user': 'pebbles', 'active': false }
]
findLastIndex(users, ({ user }) => user == 'pebbles')
// => 2
Name | Type | Attribute | Description |
---|---|---|---|
array | The array to inspect. | ||
predicate | The function invoked per iteration. | ||
fromIndex | The index to search from. |
