destructuring assignment default value : <p>I am learning javascript and I got kind of stuck with ES6 syntax while trying to give a default value to a variable when destructuring.
Basically, I am trying to assign a variable giving the value of an object's property to it and if the value is false/null/undefined, I want it to be an  empty object.
For example,</p>

<pre><code>let foo = { 
            prop1: 'hello!',
            prop2: null 
           }

const prop1 = foo.prop1 || {}
const prop2 = foo.prop2 || {}

console.log(prop1) //  hello!
console.log(prop2) //  {}
</code></pre>

<p>👆This is what I want and 👇 is ES6 sugar syntax I thought as equivalent to above(it doesn't work tho..)</p>

<pre><code>let foo = { 
            prop1: 'hello!',
            prop2: null 
           }

const { prop1 = {} } = foo
const { prop2 = {} } = foo

console.log(prop1) // hello!
console.log(prop2) // null
</code></pre>

<p>but somehow, sometimes it seems working in React, but the other times it doesn't.. is it compatibility problem? so confusing!</p>
