Why make the code in Javascript?

Since we're talking about node versions, you should already have node in your system, therefore using javascript provides a more understandable code and easier API than bash for example.

But this might change at some point, due to javascript not being the most optimal language in terms of speed for this kind of operation which requires running terminal commands.

nvm-switcher's Issues

Split main file into modules

Currently the index.js file holds all the code for the version switching logic. I like the idea of splitting it into multiple files to make it easier to test (#1) and also for better organization and readability, since it is easier to locate yourself and comprehend the code in smaller files.

Create unitary tests

I like using jest for unitary testing. With it we would be able to test the version strings and maybe even internal functions of the main function.
