/**
|
|
* Takes a predicate and a list or other `Filterable` object and returns the
|
|
* pair of filterable objects of the same type of elements which do and do not
|
|
* satisfy, the predicate, respectively. Filterable objects include plain objects or any object
|
|
* that has a filter method such as `Array`.

|
* @sig Filterable f => (a -> Boolean) -> f a -> [f a, f a]
|
|
* @param {Function} pred A predicate to determine which side the element belongs to.
|
|
* @param {Array} filterable the list (or other filterable) to partition.
|
|
* @return {Array} An array, containing first the subset of elements that satisfy the
|
|
* predicate, and second the subset of elements that do not satisfy.
|
|
* @see R.filter, R.reject
|
|
* @example
|
|
*
|
|
* R.partition(R.includes('s'), ['sss', 'ttt', 'foo', 'bars']);
|
|
* // => [ [ 'sss', 'bars' ], [ 'ttt', 'foo' ] ]

*
|
|
* R.partition(R.includes('s'), { a: 'sss', b: 'ttt', foo: 'bars' });
