When you've said "shallow copy" , I think it's like the shallow copy in python, which changing a copy, will change the original one , but when I pop()ed an item from new array and the original one stayed intact , so I got confused why they are called shallow ? is it mean that other dimensions in the array, are behaving differently like in python. or this shallow has nothing to do with that shallow copy concept we have in python?
It has nothing to do with python. "Creates a shallow copy of an array" actually means to create the copy of elements present inside an iterable. We are not copying the array, but just spreading out or separating the elements without actually affecting the original array as both the arrays have different references pointing out. Hope this helps.
Dear Bro , in the old days we used to use web page console, but if a program is just need a console and doesn't involve Html why you don't use vscode terminal , or output to log .it's way easier . I think by installing node.js we have console on the terminal. since this is your 2nd video teaching JS , and please like the other one make it around DOM , we don't want to play tic tac toe , I personally learn it just for front end web development , I prefer this way than learning flask

console.log(foods);
greatest takeaway: ``unpacks the elements ``
Thanks bro grateful this type of education exist and is freely available
when not even documentation makes me understand, I come here, and leave with pure knowledge
Thanks bro. Very helpful for us visual learners.
i love you
oh fuck yeah, *spread it*
😂 yeah babe
spread me
This is my seal. I have watched the entire video, understood it, and I can explain it in my own words, thus I have gained knowledge. This is my seal.
GREAT! Thanks for explaining!
ok yeah this is the perfect way of explaining it. thanks!
Thanks Bro Code! :D
Big fan 🪭 Sir!! 😅. Big fan
So good. Thanks!
Great job 👍

thanks , it seems that is a copy of the existing array , independent of the original one.@@sayalimore1267

Thank you soo much bro,
You are always best.
3:08 isn't that a deep copy?
yeahh...same doubt
Why the Spread Operator isn't three commas I'll never understand. (,,,spread)
It looks visualy awful haha
