Static Methods

filter<K>(bool fn(K elem)) → List<K> Function(List<K> list)

Returns a new list in which fn(every element on list) returns true Call like FP.filter<K>(fn)(list)

map<K, V>(V fn(K elem)) → List<V> Function(List<K> list)

Returns a new list where each element of list is transformed by fn. If V is nullable, and fn returns null, null will be added to the list. Otherwise, use return null to skip these elements. Call like FP.map<K,V>(fn)(list)

onEvery<K>(void fn(K elem)) → void Function(List<K> list)

Runs fn on every element of list. Call like FP.onEvery<K>(fn)(list)

reduce<K, V>(V fn(V acc, K elem), V acc) → V Function(List<K> list)

Reduces acc by calling fn on every element of list. fn should modify acc and then return it. Call like FP.reduce<K,V>(fn, acc)(list)
