docs: /// Function without /////////////////////////////////////////////////////  (seq:Sequence, value[, pred:Fn]) ↦ Array  Returns a array without elements that match `value`, with the comparison optionally defined by a predicate function.  If a predicate function is not given, the strict equality comparison (`===`) will be used.
