great explanation. Why is the fs module preferable to the fs/promises module regarding memory allocation and performance?

[@Netpilation]

for those who are wondering why do we this stream based file opertion , it is solely used for optimitztion and effecient utilization of resources . when you are using callback based file operations or syncrouns , as soon as a file is read the whole data is stored in the memory in a buffer object whose size depends upon the ram you have , if you have like a file whose size exceed your memory size then this code slow down your pc because of unavailabilty of the ram ]

[@pankajwp]

Great tutorials, Can you provide examples fro duplex and transform stream type,
as the first two are more commonly found in most of the node js tutorials

[@bibekgupta4134]

duplex : websockets
transform: file conversion, file compressions, uploading files

[@iustin4172]

great series. but i can see that you have autocomplete for object properties (5:14) for highWaterMark. i dont have that. how do i enable that? is that an addon or something? i have installed the @types/node package but i still dont have it. the autocomplete works fine for the method names. also the code works fine if i write the properties by hand, but having an autocomplete would be nice.

The best of the best 🤗🤗🤗 tnks alot

[@ipshitadey3829]

Great explanation on Stream ! can anyone tell me when is data event triggered in the above scenario. Only event listener for read event was there, but when was the event triggered?

[@khedr433]

it's triggered if there were any data in the file
if the file was empty it won't be triggered

[@Netpilation]

as soon as a chunk is full stored into the buffer the data event is emitted

[@ayoubtahir2116]

Can you do a video about the rtk query (redux), I haven't found anyone who explains it well, I think you are the only one who can

[@angelofdeath2332]

he has videos about redux and redux toolkit. Look it up on the playlists.

[@frontend_ko]

thanks teacher 28

[@Ga2-20]

Do you know how to write something like ytb mp4 dwnloader or converter? :)

[@mazharimam9216]

Can anyone tell me tho we had readFile and writeFile to read nd write then why this? 🤔. I have followed all the lectures from starting May be I have missed something in between. So let me know please.

[@AmitKumar-cp6mx]

Actually readFile and writeFile methods first store whole data into temporary memory and then do single paste. It can occupy whole of the storage or can reduce optimization if we have file containing huge amout of data.this can be prevent with the help of steams which store only a small amount of data "chunk" And do paste continuously until whole of the data is transferred or read from one file to other . Thus it's very memory efficient as it occupy memory equals to "Highwatermark" Value set to stream

[@engkunasya]

basically this is a "copy" and "paste"
