implement Object.is()

Question

Object.is() is similar to === except following cases

Object.is(0, -0) // false
0 === -0 // true

Object.is(NaN, NaN) // true
NaN === NaN // false

Here is the detailed spec, can you implement your own is()?

Code

/**
 * @param {any} a
 * @param {any} b
 * @return {boolean}
 */
function is(a, b) {
  // your code here
}
