JS Daily #37 - Same Key in Object

What is the output of following code?

const obj = {
  a: "Apple",
  b: "Banana",
  a: "Orange"

The output is:

  a: "Orange",
  b: "Banana"

In the example above, "Apple" and "Orange" are assigned to same object key(a). In such cases, last value assigned is saved to the key. That is why "Orange" is in key a.
