Zsh has an extremely powerful and flexible system of programmable widgets (zstyle), key bindings (bind), autocompletion (compinit), formatting (zformat), option parsing (zparseopts) and much more.
Some of the more well, and lesser known, parts or tidbits of wisdom I found out myself and researched online, shall be gathered here.
This assumes a baseline zsh with antigen setup leveraging the libraries found in oh-my-zsh.

In Node.js global package installs should only be done for those tools where we need to have global $PATH access to that bin/executable. That is to say, when we need command line access to the command at any path in our file system tree.
The following list of packages are some commonly found in my global assembly:
clean, elegant and succinct JavaScript derivative: drop brackets and enter significant white space, often used by me for .litcoffee

This example builds a random tree using the Reingold-Tilford "tidy" algorithm, as described in "Tidier Drawings of Trees" and implemented by d3.layout.tree. As each node is added to the graph, it enters from the previous position of the parent node. Thus, the existing nodes and the new node transition smoothly to their new positions. The animation stops when 500 nodes have been added to the tree.
