{{alias}}( collection, n, predicate[, thisArg ] )
|
||
|
|
Tests whether a collection contains at least `n` elements which pass a test
|
||
|
|
implemented by a predicate function, iterating from right to left.
|
||
|
|
|
||
|
|
The predicate function is provided three arguments:
|
||
|
|
|
||
|
|
- `value`: collection value
|
||
|
|
- `index`: collection index
|
||
|
|
- `collection`: the input collection
|
||
|
|
|
||
|
|
The function immediately returns upon finding `n` successful elements.
|
||
|
|
|
||
|
|
If provided an empty collection, the function returns `false`.
|
||
|
|
|
||
|
|

|
||
|
|
|
||
|
|
n: number
|
||
|
|
Minimum number of successful elements.
|
||
|
|
|

|
||
|

-------
|
||
