Homebrew installs nvm but nvm can't be found afterwards?

Question

I\'m using homebrew and oh-my-zsh on a fresh OSX 10.10.1 install. I got nvm via homebrew and then attempted to run it but

Answer 1

The reason you would need to reload your bash profiles or any other bash files might be because the command nvm may not be a program but a function that is defined and can only be used if the corresponding bash file is sourced.

On a system that I checked

which nvm 

does not work but

nvm list

does. This means that you can use the word "nvm" to invoke something. That something isn't a program. In the current case, it is a function which can be verified by

typeset -F | grep -P ' nvm$'

which outputs

declare -F nvm

which means nvm is a function, whose body can be inspected by doing

type -F nvm
