Pro tip: Use `async/await` with fetch to avoid callback hell. Makes understanding javascript post requests way less messy.
Example:
```javascript
async function sendData() {
try {
const response = await fetch('your-url', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ key: 'value' })
});
const data = await response.json();
console.log(data);
} catch (err) {
console.log('RIP:', err);
}
}
```
Also, Chrome DevTools > Network tab is your BFF for debugging these.
Example:
```javascript
async function sendData() {
try {
const response = await fetch('your-url', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ key: 'value' })
});
const data = await response.json();
console.log(data);
} catch (err) {
console.log('RIP:', err);
}
}
