Thanks Justin. This is one of the best solution on the internet. Keep creating.

Bro you have killed it with this tutorial. Thank you so much man, seriously best explanation of bubble sort. Reversing the pairs, refactor was so clear to understand

Thank you for explanation. This was my solution before I watched the rest of the video.

function bubblesort(array) {

let length = array.length;

while(length > 0) {
for(let i = 0; i < length - 1; i++) {
if (array[i] > array[i + 1]) {
const temp = array[i];
array[i] = array[i + 1];
array[i + 1] = temp;
}
}
length -= 1;
}

return array;
}

Great video. it would be nice if you explain the complexity of the solution. it will really help someone preparing for interviews.

the best explanation I've ever seen on youtube, thank you so much!

Thank you very much, working my way through project Odin and I was struggling to understand algorithms and other coders solutions.

I understood more with this 10 minutes video than I did with 2 hours at college

Yo, love this tutorial man!!!! Your logic makes so much sense to me mate! Thanks for sharing your knowledge! :)

[WatsonGT]

Thanks for the explanation! Great tutorial!

why should we do array.length-1 and lower array.length - 1 - i, i checked with this (just array.length for i and for j ) and it worked also

Suggestion - You can hide problem statement while explaining the coding part, so that we can watch coding lines clearly. Your video is helpful. Thanks. 😊

Great tutorial, easy to understand and very concise!!! Quick question on concept of 'pure function', at 7:45, you mentioned that a 'pure function' should NOT change the value of the parameter passed into the function. Can I ask if I can understand this statement is a special case falls into the commonly said 'Pure Functions Produce No Side Effects'? Meaning that 'change parameter value is a side effect'. If anyone could be kindly enough to clarify If my understanding is correct. Thanks!!

Hello Justin, love your channel, but i want to understand that [arr[j], arr[j+1]] = [arr[j+1], arr[j]], why this do the swapping ? I have never seen that way

[juliairwin]

I'm new in using for loop in javascript. Can someone explain this code.
const temp = array[j];
array[j] = array[j+1];
array[j+1] = temp

[juancaca]

not a clear explanation to be honest :/
