Some minor spelling issues:

• Given are the implementations of these functions
• We want to limit infinite sequencers like factorialSeq
• You should implement the addLimit(limiter) method on the pipeSeq() function
• stepLimiter is a function that receives the max number of elements

Would be nice to have these minor spelling issues resolved:

• Given are the implementations of these functions
• Using in this way: / They are used in this way
• This function allows you to pipe generators to other functions.
• optionally some parameters to be passed to the sequencer and returns an object with two methods:
• returns the piped sequencer function.
• Here is an example to illustrate the intended behaviour:
• We could create the piped sequencer like this: / The piped sequencer is created as follows
• This function sums the values of the sequence.
• You should also implement the isEven pipe function:
