both assignments completed finally learnt how to use splice method in array.

[@Torpedo91]

for anybody whose program is not creating new entry in user.json, 1.) Try to console.log() the users after pushing the new entry. 2.) If you see the new entry there, and the code doesn't have syntax mistake then the problem is directory path of user.json copy this code and paste it in the program, const file_path = __dirname + '/users.json'; put this file_path in fs.writefile and try again.

for me only the new ids are getting added in the data and not the entire user info ...anything you could suggest?

Amazingly explained. Thank you 💙 DELETE request: app.delete("/api/users/:id", (req, res) => { //Get the id of the user const id = Number(req.params.id); //Find out the index of the user with above id from the array "users" const userIdx = users.findIndex((user)=> user.id === id); //Get the deleted user object using splice. Mind we need to get the object and not array as returned by splice method, so '[0]' satisfies this requirement. The resulting object is just for the sake of displaying, you may neglect storing it if you don't want to display. const delUser = users.splice(userIdx, 1)[0]; //Write the changes into the json file. fs.writeFile("./MOCK_DATA.json", JSON.stringify(users), (err, data) => { return res.json({ status: "success", delUser }); }); })

Here is a Solution for the Patch request Hope it Helps app.route("/api/users/:id") .patch((req, res) => { // getId stores the Id from the given Parameters in the URL. const getId = Number(req.params.id); // body stores the body in which we've to make changes. const body = req.body; // Finding the user Id from the user array. const userIndex = users.findIndex((user) => user.id === getId); // If we found a user with its Id then gotUser stores that object. const gotUser = users[userIndex]; // Here gotUser has the user Object and body has the changes we have to made. const updatedUser = { ...gotUser, ...body}; // After Merging them, Update the users Array. users[userIndex] = updatedUser; // Lastly, write the changes into the json file. fs.writeFile('./users_mock_data.json', JSON.stringify(users), (err, data) => { return res.json({ status: "Success", updatedUser}); }) })

[@user-rw8en1jp4t]

Thanks!, this solution is very readable and clear

[@hidev4615]

this can be done using map easily, //you should update this logic: .patch((req, res) => { const id = Number(req.params.id); const { last_name } = req.body; const newUsers = users.map((user) => { if (user.id === id) { return { ...user, last_name }; } else { return user; } }); fs.writeFile('./MOCK_DATA.json', JSON.stringify(newUsers), (err, data) => { return res.json({ status: 'successfully edited user', id }); }); })
