I’ve been practicing my JavaScript for the HackReactor interview on the 20th (wish me luck by the way). They sent around an email saying to be prepared so you didn’t have to reschedule (I’m suddenly glad I couldn’t get an appointment straightaway). They recommended being able to get through all the easy challenges on Coderbyte in < 5 minutes. Yikes? Surprisingly not. I’m having a lot of fun.

There are a couple things I’ve obviously forgotten (I had to look up the regex to keep only alpha characters, I suck at regex), but I’m pretty fast. I’m also realizing just how not amazing I am at the trickier puzzles. There are one or two in there that I still don’t understand, even after I caved and looked up how others solved them (Array Addition I, I’m glaring at you).

There are 26 easy challenges. I’ve decided to run through at least 10 a day, so I finished the first 10 today and uploaded them to my GitHub. My favorite one so far was the TimeConvert, which took a number (e.g. 126) and converted to the amount of hours and minutes (e.g. 2:6). I could have made it prettier by added a preceding 0 in the minutes, but the goal of these is speed and the instructions didn’t ask for that pretty extra. This was my favorite because I just have this weird love for modulus. The code to solve it:

1
2
3
4
5
6

function TimeConvert(num) {
  var minutes = num % 60;
  var hours = parseInt(num/60);

  return "" + hours + ":" + minutes;
}
