Awesome. Really I was very afraid from JavaScript, didn't understood how to do coding. But you make my life easy. Thanks, God bless you.

I've been stuck on the idea of parameters for an entire day until I watched your video. Your videos are clear, succinct, and easily digestable. Thank you!

I fell in love with JavaScript because of your videos . Thank you so much for that.
Here is a request. Could you please make a video on modules v/s components.
Thanks in advance

What if we have function takes a complex object as param ? Example: add({a:10, b:{rate: 20}});
and in add(), logic is: a + obj.b.rate ?
Expected result: 30

[Albertmars]

how do i reference the default object? add = ({a=3, b=3}={}) =>{ return a + b}

Thank you for making another awesome video and sharing it with all of us! I always give your videos in nice thumbs-up and of course I am subscribed. I am still struggling with the spread operator, I suspect it has many uses if I could wrap my head around it a little better.

In 2:30 you need to be carefoul.

let add = (a, b) => {
a = a || "dog"
console.log(a, b);
}

add("", "cat"); //"dog, cat", I expected: ", cat"
add(0, "cat"); //"dog, cat", I expected: "0, cat"

Example from 1:50 is safer
