To update a JSON object using JavaScript, we can use a loop.
For instance, we write
for (const o of jsonObj) {
if (o.id === 3) {
o.username = "Thomas";
break;
}
}
to loop through the objects in the jsonObj array.
In the loop, we find the item with id 3.
If it’s true, then we set its username property value to 'Thomas'.
Conclusion
