Those are fairly indistinguishable. It's when they start removing letters from words to save... debug symbol bytes or something? That's when c-style naming annoys me.
npm -g i package-name
Like why would you teach people to do this? I understand people needed to save precious bytes in the sixties so we have cat and ls but saving 192 bytes or whatever with shorter variable names is not a worthwhile tradeoff anymore. npm install --global @scope/PackageName
At least the hi and lo can get more meaningful names. And over time we can write this in another language with private/scoped methods.
