Run any Node.js version 10x faster than nvm

This is portrayed as an alternative to NVM but for what NVM does it seems more awkward. NVM installs by bash because you do it before installing NodeJS because the script is going to download only the version you want. This efficiently solves the problem "install the target version of node for your application" on your server and "install the target for each application" on your workstation.

Compared to NVM's main use case - this NVE software is bootstrapped with NodeJS and 150 modules so on a server you just want to install the required NodeJS version as step 1-of-1, on your workstation maybe this can compete with NVM.

The 10x faster stuff is silly too. NVM just puts a symlink to whichever version of NodeJS you're using. The benchmark is contrived to execute code using NVM, which is one way, but in practice you use NodeJS directly when you use NVM. Executing NVM superfluously adds a lot of benchmark time.

    $ nvm use 8.12.0
    $ time bash -i -c node\ --version
    v8.12.0

    real    0m0.364s vs 0.692 through NVM
    user    0m0.330s vs 0.639
    sys     0m0.051s vs 0.78

Where this software seems different to NVM is in running multiple NodeJS versions within the same application so you could execute logic across disparate versions. That might be interesting with pinning down specific functionality from dependency/node combinations.
