Determine whether two values are the same value

The Object.is() method determines whether two values are the same value.

Object.is('foo', 'foo');     // true

Object.is(null, null);       // true

Object.is(Nan, Nan);       // true 😱

const foo = { a: 1 };
const bar = { a: 1 };
Object.is(foo, foo);         // true
Object.is(foo, bar);         // false
