Tried multiple videos but this video cleared this concept better for me.
Thanks 😊

I've been studying JS, and I've been learning a lot. I love this video. Something I would like to add, is that if you're using it on the left side of the = operator it works as the rest pattern, but if you use it on the right side it works as spread. Please provide feedback!

const arr1 = [1, 2, 3];
const arr2 = [...arr1, 4, 5, 6];
Output is [1, 2, 3, 4, 5, 6];

But

const arr1 = [1, 2, 3, 4, 5, 6];
const [a, b, c, ...d] = arr1;

Output
a is 1
b is 2
c is 3
d is an array with the rest of the elements. So in this case, ... Creates a new array that contains the rest of the values.

I want to create a shallow copied array. Which syntax I should use?
//Rest syntax
const [...abc] = array;
Or
//Spread syntax
const abc = [...array];
