+The spread operator can also copy enumerable properties from one or more objects onto a new object:
+```javascript
+const obj1 = {
+  a: 1,
+  b: 2,
+  c: 3
+};
+
+const obj2 = {
+  d: 4,  
+  e: 5,
+  f: 6
+};
+
+const newObj = {...obj1, ...obj2);
+
+// newObj = { a: 1, b: 2, c: 3, d: 4, e: 5, f: 6 }
+```
