Programming exercise #1 - find every second and add new line

Recently, I found interesting topic on SO, about parsing string in JS.
The exercise is:
Create function, that takes a string and returns string. Every second word should have added new line character "\n".
For example

let stringToParse = `How good is have account on and create new posts`
let result = "How good
is have
account on
StackOverflow and
create new
posts
