6 | * Returns a new list excluding the leading elements of a given list which
|
7 | * satisfy the supplied predicate function. It passes each value to the supplied
|
8 | * predicate function, skipping elements while the predicate function returns
|
9 | * `true`. The predicate function is applied to one argument: *(value)*.
|
10 | *
|
11 | * Dispatches to the `dropWhile` method of the second argument, if present.
|
12 | *
|
13 | * Acts as a transducer if a transformer is given in list position.
