Thanks everyone for commenting/contributing! I made this in college for a class and I no longer really use the technology. I encourage you all to help each other, but I probably won't be answering questions anymore.

This article is also on my blog: https://emilykauffman.com/blog/install-anaconda-on-wsl

Steps to Install Anaconda on Windows Ubuntu Terminal

Install WSL (Ubuntu for Windows - can be found in Windows Store). I recommend the latest version (I'm using 18.04) because there are some bugs they worked out during 14/16 (microsoft/WSL#785)
Go to https://repo.continuum.io/archive to find the list of Anaconda releases
Select the release you want. I have a 64-bit computer, so I chose the latest release ending in x86_64.sh. If I had a 32-bit computer, I'd select the x86.sh version. If you accidentally try to install the wrong one, you'll get a warning in the terminal. I chose `Anaconda3-5.2.0-Li

Nested Routers in Express.js

Express makes it easy to nest routes in your routers. But I always had trouble accessing the request object's .params when you had a long URI with multiple parameters and nested routes.

Let's say you're building routes for a website www.music.com. Music is organized into albums with multiple tracks. Users can click to see a track list. Then they can select a single track and see a sub-page about that specific track.

At our application level, we could first have a Router to handle any requests to our albums.
