/*
Description:
Write a function that takes as an input a string of words, and returns the number of words in that string.
For example:
str = “Houston, we have a problem” # return 5
str = ” Toto, I’ve got a feeling we’re not in Kansas anymore. ” # return 10
Notes:
Contractions (such as “I’ve”, and “we’re”) count as one word, not two.
Whitespaces at the beginning and end of a string should be ignored.

function wordCount(str) {
return str.trim().split(` `).length
}
