Day 32

Advanced Javascript Topics

We are blazing through the MEAN stack at the moment. We've yesterday we've finished two chapters (fundamentals and OOP) and now we're going through all the advanced topics. These topics include callbacks and event handling. Callbacks are just functions that are passed through another function as a parameter. Why is it important? Delegation and event handling. Think of delegation as a parent function continuing whatever is coded into it and the callback being a function that runs in the background or along side the parent function. This is where event handling comes in, the callback function runs if the event is met or the callback returns something when a callback happens!

The assignments weren't too hard, it covered most basic callback functions. I don't know whether this is a good thing since I've heard callback functions are very useful and used a ton in industry or maybe callback functions is only as complicated as the functions you put into it. Anyways, that's it for today's post.

I also want to mention that algorithms has been kicked up a notch. After linked list last week in Python, we are now doing recursive functions for the first week of the 2nd stack. I remember hearing about it from CSE 143 students and I can see why it's so hard to grasp. The trick I learned so far is that recursions are essentially for loops or while loops. So, do the problem first using for or while loops and eventually translate that into a recursive function.
