Anybody know any good resources to challenge myself or just review more complicated topics in Java, Javascript, or C++??

Thank you

code academy(https://www.codecademy.com/) is how I've learned most of the languages I've ever coded in.

w3 schools is really helpful for learning JavaScript!

Good luck!

w3schools teaches bad practices. I'd suggest the Mozilla Developer Network instead for reference. Are we talking just vanilla JavaScript here?

If you're not already familiar with ES6, I'd recommend picking it up. Maybe do a project in React Native? :D That really teaches you some useful skills.

For C/C++, what sort of topic are you interested in? If you want to get a bit low-level in C/C++, try this: https://scs.hosted.panopto.com/Panopto/Pages/Sessions/List.aspx#folderID=%22b96d90ae-9871-4fae-91e2-b1627b43e25e%22

It's pretty challenging and definitely delves into the more complicated side of things. I'd strongly recommend getting or finding the associated CS:APP book since it contains the challenges that make the course what it is.

Can't really help with Java since I don't know of any super-challenging OOP review things out there.

Oh, there's also the bots on codefights (codefights.com); most of them are pretty weak but some are decent. Other players on that site, too. Pretty fun way to burn time if algorithms are what you're into.
