Hi, I'm seeing issue with array.pop(). I have a array let arr=[1,2,3,8,3 2,1], str='';
for (let j of arr){
str=str+arr.pop(j)
}
Expecting output is 1238321
But the actual output is 1238.
I checked many times with different elements also, still seeing same issue. Did anyone else facing this issue? Any suggestion on how to fix this issue-Thanks

This is so bad. It's just walking through the code without explaining the concepts such as recursion. Not even a visual display of the call stack to show the different recursive calls.

Please cover DSA in js deeply
guys, is this playlist is sequential – do all general topics are covered here? I mean, I see some videos from this playlist in other playlists of this channel, and on this channel so many playlists with JS, that I don't even know what to go through.
That's amazing ! thanks
Hello sir I was understanding the heap data structure and I found a bug in remove() method. When we create a min heap with these values [1,5,9,10,12] and remove the smallest value from it. It returns [ null, 5, 12, 9, 10 ] instead of [ null, 5, 10, 9, 12 ] which is not correct. So I implement the below code to fix this bug
this.remove = function () {
if (heap.length > 2) {
let smallest = heap[1];
// Move the last element to the root
heap[1] = heap.pop();
let current = 1;
while (current < heap.length) {
let left = current * 2;
let right = current * 2 + 1;
let smallestChild = heap[right] && heap[right] < heap[left] ? right : left;
if (heap[current] > heap[smallestChild]) {
[heap[current], heap[smallestChild]] = [heap[smallestChild], heap[current]];
current = smallestChild;
} else {
break;
}
}
return smallest;
} else if (heap.length === 2) {
return heap.pop();
} else {
return null;
}
};
Man this got me thinking. But loving it!!!! I guess that's the beauty of programming.
At 40:56 I am confused by the min height definition. A leaf node has no children so how is the min height 1? Also don’t you have to have a complete binary tree to find min height?
Good course. Could use an es6 update! Found myself refactoring a lot.
im new to coding, i started with web dev a few months ago and i only know python and javascript. I want to be a web developer in future, so is dsa important for me?
Is this full course about data structure
Can you give me some documents?
These lessons are great! Though while going over these explanations of what each data structure is and how to code one from scratch, I'm wondering: what is the real takeaway from these explanations? Is it more valuable to know how, for example, to code a Set from scratch or is it better to just be familiar with the data structure and its methods? My guess is that most job interview questions involve a problem whose solution requires the use of one data structure vs another. Do interviewers ever ask candidates to actually build one themselves?

My Question is where can we use this in web dev projects ?
At 05:00 minutes in, a function is described (Stack()) with several properties and methods. Then it looks like an instance is made of that function (myStack = new Stack(). I'm confused as I thought that this was only possible with classes that use constructors.
To my question: "can you create an instance of a function like you would an instance of a class in javascript?"
Chat GPT says: "No, functions are not objects in JavaScript and cannot be instantiated like classes. However, functions can have properties and methods added to them just like objects."
Can someone explain why is being done?
