About the *reduce* method, *accumulator* does not starts at *0, * at least you specify it: *[1, 2, 3, 4, 5].reduce( (acc, value) => acc+value, 0 );*

If you do not specify the *acc value, * it will be the first element of the array at the first iteration, and value will be the second one.

Loved your work man. I was back to a js project after few years and wanted to check what's in practice nowadays. This video helped me to learn that in just 5 mins. Great job man and very precise. Thank you. 👍 ☺

[taifbakshi]

it would be great if you'd dive deep into some of these methods. like, reduce(), find(), filter()

About the *sort* method, it does not works for me. I use the same code than you, and I get the same original array:

const numbers = [1, 3, 4, 5, 2];
const sortedArray = numbers.sort((a, b) => a < b);
console.log(sortedArray); *// [1, 3, 4, 5, 2]*

const numbers = [1, 3, 4, 5, 2];
const sortedArray = numbers.sort((a, b) => a > b);
console.log(sortedArray); *// [1, 3, 4, 5, 2]*

How do you make that works in your video ??? 😲

Warning!!! Everybody pay attention at the method sort. If you want to sort ascending order in condition do not use a > b instead of a - b and vice verse.

The sort() implementation of this video tutorial doesn't work.

According to MDN Reference :
The sort() method sorts the elements of an array in place and returns the sorted array. The default sort order is ascending, built upon converting the elements into strings, then comparing their sequences of UTF-16 code units values.

The time and space complexity of the sort cannot be guaranteed as it depends on the implementation.
