+# Object Initialization With Shorthand Property Names
+
+If I have some variables:
+
+```javascript
+const one = 1,
+  two = 2,
+  three = 3;
+```
+
+and I'd like to initialize an object with them, I'll generally do something
+like the following:
+
+```javascript
+const obj1 = {
+  one: one,
+  two: two,
+  three: three
+};
+// Object { one: 1, two: 2, three: 3 }
+```
+
+That seems pretty standard, but with ES6 comes a feature called *shorthand
+property names* which makes that look verbose and redundant. If you already
+have properly named variables, they can be used as a short hand for both the
+key name and variable value:
+
+```javascript
+const obj2 = {
+  one,
+  two,
+  three
+};
+// Object { one: 1, two: 2, three: 3 }
+```
+
+See the [MDN Docs for Object
+Initializer](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Object_initializer)
+for more details.
