What IDE could I use that:
1) Doesn't require me to switch to vim or emacs key bindings 2) Has strong auto completion for web development 3) Is more performant than electron style applications
I have noticed that IDE's based on Scintilla are very responsive. Much better than ones based on Java frameworks and vastly faster than VSCode. The memory usage is much smaller. Current medium sized project I have open is using 45mb of memory.
A suggestion is to do the brain dead thing I did and look at the lists of IDE's on Wikipedia and try the ones that might work for you.
