Help with constructor

I have an object constructor which expects a string input (initialData). The object constructor returns an object that contains the following methods:
a.      getSentences: this method should return an array of the sentences contained in ‘initialData’
b.      getWords: this method should return an array of words in ‘initialData’ when there is no parameter passed in. Optionally, when there is a parameter passed in that is a number, return the words in the sentence indicated by the input parameter. Not sure how to do this?

Sample input:

var sampleData = 'My experience in the nature study area was full of surprises. First of all, many unexpected creatures crossed our path! For example, as soon as we left the parking area and entered the grassy path, a long snake slithered along the edge of the high grass and quickly disappeared. In addition, I was surprised by how colorful the grasses, which from a distance all appear to be green, actually are.';

Sample outputs:
a.   array with sentence in each element
  res[0] = My experience in the nature study area was full of surprises.
  res[1] = First of all, many unexpected creatures crossed our path!
etc.

b. no parameter passed
   res1[0] = My
   res1[1] = experience
b if parameter passed 3 e.g., returns first 3 words of every sentence
   res1[0] = My experience in
   res1[1] = First of all
