Document quick fix (or whatever it's officially called)

Code
not entirely applicable, but this is what I had which caused me to get confused

const fs = require("fs");

Expected behavior:
Commandline tsc should behave the same as editor integrations

Actual behavior:
The "quick fix" feature, which appears to be called "code fixes" in the codebase and googling the messages led me to the json file which refers to them as "suggestions", only appears to exist in the typescript server.

As a newcomer this had me extremely confused. I was running tsc on the commandline and getting no errors, but seeing squiggly lines and messages in my editor (atom, in this case).

I was unable to find any documentation about where the message 'require' call may be converted to an import was coming from, or that this was a hint that typescript was able to fix my code for me.

It would also be helpful if the tsc client was able to list the code fix suggestions, even if giving it a way to apply them would be too complex.

Inizia confrontando il comportamento di tsc dalla riga di comando con il TypeScript server e le integrazioni dell’editor descritte nell’issue. Traccia la terminologia di code-fix nella codebase di TypeScript e nel relativo message JSON, quindi determina se la sola documentazione copre la lacuna o se è necessario anche elencare i suggerimenti in tsc; il lavoro è completato quando la terminologia e il comportamento supportato sono documentati chiaramente.
