How to write JSON to files
const fs = require('fs');
// create a JSON object
const user = {
"id": 1,
"name": "John Doe",
"age": 22
};
// convert JSON object to string
const data = JSON.stringify(user);
// write JSON string to a file
fs.writeFile('user.json', data, (err) => {
if (err) {
throw err;
}
console.log("JSON data is saved.");
});
