// 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.
function confirmEnding(str, target) {
let endOfStr = str.slice(str.length - target.length);
return endOfStr === target;
}
confirmEnding('Bastian', 'an');
// OR
function confirmEnding(str, target) {
return str.slice(-target.length) === target;
}
confirmEnding('Bastian', 'n');
