Different between fs.writeFile and fs.writeStream
I'm a little confused between the 2 methods, hope somebody could enlighten
me on the different between
fs.write are for low-level access, similar to what you get when you code in C.
fs.open opens a file and
fs.write writes to it.
fs.WriteStream is a stream that opens the file in the background and queues writes until the file is ready. Also, as it implements the stream API, you can use it in a more generic way, just like a network stream or so. You'll e.g. want this when a user uploads a file to your server - take the incoming HTTP POST stream,
pipe() it to the
WriteStream. Very easy.
fs.writeFile is a high-level method for writing a bunch of data you have in RAM to a file. It doesn't support streaming or so, so it's a bad idea for large files or performance-critical stuff. You'll want this if you write out small JSON files or so in your code.
