— Also look at util.promisify


const fs =
const { promisify } =

const mkdir =
const readFile =
const writeFile =

.then(() =>
.then(data =>
writeFile('stuff/write.txt', data));

— Okay const means constant and that variable fs can't be changed or reassigned

— Yep

— Always use const unless you plan to reassign

— Okay thank u i will note that down now

— Not really, all it is, is an event loop and cooperative scheduler, things that can be used for any purpose

— It basically lets seperate things get processing time without returning

— Single-threaded

— Applications will use system calls to the kernel for specific things. Stuff like yield DISPATCHER_WAIT(pid); which tells the scheduler to not run the program's main thread again, only running the event loop, until the dispatcher gets an IPC message from the specified pid

— There will be messaging between running programs, so you might want to wait for a message sometimes.

— I will also be disabling Node automatic GC via C++
