For questions about writing to a file. It could be referencing appending data, rewriting all existing content, or other related uses of functions that programmatically edit files. It is not limited to a certain language.
This tag is most often used when someone wants to add/insert content to a file programmatically. One example is in the Node JS function fs.writeFile, which is used to create files and write to them.
This is an example script which shows the usage of fs.writeFile to write a string to message.txt.
// Node JS
const fs = require('fs');
const data = new Uint8Array(Buffer.from('Hello Node.js'));
fs.writeFile('message.txt', data, (err) => {
if (err) throw err;
console.log('The file has been saved!');
});
Make sure to pair this tag with a language tag as writefile is generally not specific enough to describe a complete question.
