• Difficulty: 1/5

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

Remember to use Read-Search-Ask if you get stuck. Try to pair program. Write your own code.

• String.substr()

Problem Script:

function end(str, target) {
  // "Never give up and good luck will find you."
  // -- Falcor
  return str;
}

end('Bastian', 'n');

Explanation:

The function is a whole Boolean operation. You need to return true if the first argument ends with the second argument. This means that for the problem script, it should return true for the end('Bastian', 'n'); case.

Hint: 1

Take a look at how substr() works. You will be trying to get the last Nth characters.

Hint: 2

To get the Nth-to-Last character you will use length() and turn it into a negative number.

Hint: 3

Check that you have the proper syntax and that you use === to compare.

My code:

function end(str, target) {
  if (str.substr(-target.length) === target)
    return true;
  else
    return false;
}

My Code Explanation:

We use the subtring() with the negative value of the lengths of target. We could use -1 to get the last element but if the target is actually longer than one letter then the program will provide the wrong information. The we return true or false as needed.
