confirmEnding.js
// Confirm the Ending

// Check if a string (first argument, str) ends with the given target string (second argument, target).

// This challenge can be solved with the .endsWith() method, which was introduced in ES2015. 
// But for the purpose of this challenge, we would like you to use one of the JavaScript substring methods instead.

// Sample Input

// "Bastian", "n"
// "Connor", "n"
// "Open sesame", "same"

// Sample Output

// true
// false
// true
