Below is a list of notes made for the course JavaScript: The Weird Parts.

	# If you come from bash you might have to change your $PATH.
	# export PATH=$HOME/bin:/usr/local/bin:$PATH

	# Path to your oh-my-zsh installation.
	export ZSH="$HOME/.oh-my-zsh"

	# Set name of the theme to load --- if set to "random", it will
	# load a random theme each time oh-my-zsh is loaded, in which case,
	# to know which specific one was loaded, run: echo $RANDOM_THEME
	# See https://github.com/ohmyzsh/ohmyzsh/wiki/Themes

	# You need to give this file permission to execute by doing the following...
	# chmod +x f.sh

	# Add an alias named f to your .zshrc file like this:
	# alias f="/Users/brad/Documents/shell-scripts/f.sh"

	code "$(find ~/Documents ~/Desktop ~/Sites ~/Local\ Sites -type d \( -name "node_modules" -o -name ".next" -o -name ".git" -o -name "vendor" -o -name "wp-includes" -o -name "wp-admin" \) -prune -o -type d \| fzf)"

	# todo someday
	# currently it only searches for folders, but it would be nice if I could search for zshrc or specific files, but I'm not sure if that will include too many files and be slow...
