• iTerm2
• Z-shell
• Oh My ZSH!
• Powerlevel9k
• Nerd Fonts, which are Powerline-derived fonts, particularly my favorite - Hack Nerd

The Promise All Problem

in case of processing a very large array e.g. Promise.all(A_VERY_LARGE_ARRAY_OF_XHR_PROMISE)

which would probably blow you browser memory by trying to send all requests at the same time

solution is limit the concurrent of requests, and wrap promise in thunk

Promise.allConcurrent(2)([()=>fetch('BLAH1'), ()=>fetch('BLAH2'),...()=>fetch('BLAHN')])
