Thanks for compiling the exercises and great to see you "learning-by-doing"! 

While your code work, there are a few that you can improve. For example, reversing string can be as simple as:

const reverseStr = str => str.split('').reverse().join('');

Of course, this is ES6. But it would be minimal with ES5 as well. Cheers!
