{{alias}}( collection, predicate[, thisArg ] )
|
|
Tests whether at least one element in a collection passes a test implemented
|
|
by a predicate function.

The predicate function is provided three arguments:
|
|
|
|
- `value`: collection value
|
|
- `index`: collection index
|
|
- `collection`: the input collection
|
|
|
|
The function immediately returns upon encountering a truthy return value.
|
|
|
|
If provided an empty collection, the function returns `false`.
|
|
|
|
