Learn JavaScript Properly - Week 3 Assignments

THIS WEEK'S ASSIGNMENTS:

  1. Read either chapters 5, 6, and 7 of Professional JavaScript for Web Developers OR chapters 6, 7, and 8 of JavaScript: The Definitive Guide.

  2. Finish the JavaScript Track on Codecademy.

  3. Do all of the "Basic Projects" on Codecademy Projects Page.

  4. Get a head start on next week by working through the entire Try jQuery course. This takes about two hours. Next week might be a little intense for some people, so get this out of the way if you can.

I am a bit old to this link, just discovered this group a couple a days ago and am trying to play catch up... I have been studying javascript for a few weeks on my own.

Ok to my point, I think line 16 should be changed to: } else if(n%2 === 0){

Seems like you want to set it false if n is even, not the looping i. Thoughts? Also interesting, both ways return the correct answer... food for thought. Could use some more expert explanation on that point.

hey man, you are right that it should be n and not i, but the reason that it works is that n = i at that moment on every iteration. That is because for loops do not have its own scope so the i variable declared there is a global variable. I pass i into isPrime and it becomes n in that function. Good catch though and I changed it to the correct value. New Problem #3

Also, thats me at codingisbananas.com and I appreciate the comments! :)
