Standards checklist:

• The PR title is descriptive.
• The PR doesn't replicate another PR which is already open.
• I have read the contribution guide and followed all the instructions.
• The code follows the code style guide detailed in the wiki.
• The code is mine or it's from somewhere with an MIT-compatible license.
• The code is efficient, to the best of my ability, and does not waste computer resources.
• The code is stable and I have tested it myself, to the best of my abilities.

Changes:

This looks like a list of the flags of node's --help output. I can only see two useful aliases: node -e and node -c. Tell me the reason behind the rest. BTW there's a typo on --no-deprecation in the README and the .plugin.zsh file.
