### Working with Domain Objects
The [object API]{@link module:openmct.ObjectAPI} provides useful methods
for working with domain objects.
To make changes to a domain object, use the
[`mutate`]{@link module:openmct.ObjectAPI#mutate} method:
```
openmct.objects.mutate(myDomainObject, "name", "New name!");
```
Making modifications in this fashion allows other usages of the domain
object to remain up to date using the
[`observe`]{@link module:openmct.ObjectAPI#observe} method:
```
openmct.objects.observe(myDomainObject, "name", function (newName) {
myLabel.textContent = newName;
});
```
