How to work with String in Angular2?

Question

JavaScript

How can I implement the following task - I have a text, I filled some words in it with spaces so that it was possible to add a hyphen when clicking (implemented). I need a way that would compare the entered hyphens with the words in check by clicking on ok and give 5 points for each correct solution. Tell. please how to compare the position of hyphens in words? Here is a working example plnkr.co/LTiI1hvx2DdVFhT4jryJ ">
