We'll read a csv file in node.js both synchronously, and asynchronously. The file we're reading is a plain text, utf8 file - but you can also use fs.readFile to read a binary file as a buffer. We'll look at the differences between readFile and readFi…
In node.js, you can require fs, and then call fs.writeFile with the filename, and data to write to that file (as a string or a buffer). That will overwrite the entire file, so to just append that data to the file instead, pass an options object with…
