Snippet: Here’s an example of creating a user registration API endpoint using Node.js and Express framework:
// Import required modules
const express = require('express');
const app = express();
// Define user registration endpoint
app.post('/api/register', (req, res) => {
// Extract user data from request body
const { name, email, password } = req.body;
// TODO: Implement user registration logic
// Return success or failure response
res.json({ message: 'User registered successfully' });
});
// Start the server
app.listen(3000, () => {
console.log('Server is running on port 3000');
});

Snippet: Here’s an example of a basic login screen implementation in Kotlin:
class LoginActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_login)
// Find UI elements
val emailEditText: EditText = findViewById(R.id.emailEditText)
val passwordEditText: EditText = findViewById(R.id.passwordEditText)
