filter

• filter<T>(this: ChannelWrapper<T>, predicateFn: function): ChannelWrapper<T>

• The filter method takes a predicate function and returns a new channel. Each value inserted into the channel on which this method was called will be passed to the predicate, and only those who make the function to return true will be inserted into the returned channel. The others will be discarded.
