-Inside the constructor, add `this.position` and assign it an object with the `x` and `y` coordinates.
+When working with objects where the property name and value are the same, you can use the shorthand property name syntax. This syntax allows you to omit the property value if it is the same as the property name.
+
+```js
+// using shorthand property name syntax
+obj = {
+  a, b, c
+}
+```
+
+The following code is the same as:
+
+```js
+obj = {
+  a: a,
+  b: b,
+  c: c
+}
+```
+
+Inside the constructor,  add `this.position` and assign it an object with the `x` and `y` coordinates. Make sure to use the shorthand property syntax .
