# getObjectCopy\(object: T): T
Returns independent copy of `object`, with same prototype chain.
## Examples
```
// These are tests you can run:
export class TestClass {
prop0 = {propA: {propB: {propC: {propD: 'value'}}}};
prop1 = 1;
prop2 = 2;
doThis() {
return this.prop1 + this.prop2;
}
}
export class TestSubclass extends TestClass {
prop3 = this.doThis(); // 3
}
export class TestSubSubclass extends TestSubclass {
}
let original = new TestSubSubclass();
let copy = getObjectCopy(original);
// Make sure copy is instanceof the most distant parent:
if (copy instanceof TestClass) console.log('test 1 passed');
else console.log('test 1 FAILED');
// Make sure copy is instanceof its immediate class:
if (copy instanceof TestSubSubclass) console.log('test 2 passed');
else console.log('test 2 FAILED');
// Make sure the copy is not just a reference to the original:
if (copy !== original) console.log('test 3 passed');
else console.log('test 3 FAILED');
// Make sure it contains the inherited method:
if (copy.doThis && (copy.doThis() === copy.prop3)) console.log('test 4 passed');
else console.log('test 4 FAILED');
// Make sure deeply nested properties are included in the copy:
if (copy.prop0.propA.propB.propC.propD === 'value') console.log('test 5 passed');
else console.log('test 5 FAILED');
```
