Csound.start() directly starts performance

Dear Csounders!

in JS, when I execute await csound.start(); my csound object directly starts with performance but in docs (https://www.npmjs.com/package/@csound/browser#CsoundObj.start) it says that it “Prepares Csound for performance”. I would like to ‘drive’ my csound object manually using performKsmps() function.

I did this many times in python and c++ but never in JS so I’m not sure is this expected behavior? Should I do something different?
