About this Meetup

Note: You need to bring your own computer for this meetup.

Another Note: In this group I often recommend that you use free online services to practice coding challenges. But not everyone wants to give out their email. In case you don't want to give your email to LeetCode, Hackerrank, FreeCodeCamp, etc., one option is to make a throwaway email account on 10 Minute Mail. https://10minutemail.com/10MinuteMail/index.html If you use a throwaway email, you should be able to submit your code and see if it passes the test cases without getting unwanted emails.

Before the meetup happens I will update this description with some code challenges that we can work on. Ideally we will discuss our approach, talk about efficiency, and generally help each other out. There is a projector so we can share our code with the classroom.

Please note that I'm not a teacher, just a person who knows JavaScript, Java, and Python and likes to talk about coding, so this is not a class, it is supposed to be simply a conversation in a supportive environment.

This is an open-ended group where you can either choose your own tasks to work on, or work on the problems that I pick out. Each week I choose 3 or 4 code challenges that are variations on a theme. I will be working on those problems and those of us that finish them usually talk a little bit about our approach, our Big O notation, etc.

If you are learning a programming language for the first time, here are some beginner-level problem sets to work on:

Here are some problem sets to practice JavaScript:

Here are some more problem sets to practice Python:

As far as online courses for interview prep are concerned, I've also read that Firecode.io is nice because it determines what level you are at, then shows you exactly one problem at a time, instead of giving you hundreds of problems to choose from like other sites do.
