Your the best source I've found to teach myself JS. Seriously a gem of a channel over here. Thanks for all your hard work sir!

[ryanbooth]

This has been messing with me and causing me stress for weeks, and you explained it in just the right way. Thank you.

just what I needed, I was building a basic to do list to be run in console, but I had it way too complicated with object constructors for each day of the week (new, this keywords), I deleted it all and went back to basic arrays and your playlist is helping me alot thanks!

[rotrose]

Second round to learn this, feel much better now. Thank you.

Best professor on webdev you are the bomb bro. I taught myself a lot from your an addition. Array pop method also returns a value just like the array shift method. Pop returns the last element that was popped.

Smart way of explaining new concepts to beginners. You have my Sub sir.

It time for Steve to release a playlist on data structures and algorithms using javascript!! :)

Q1. Is there a way to delete an element from the array through a direct reference? (eg: remove 0, 1, 2... or remove "Leia") without having to use .pop each time. Or maybe a way to use .pop with a function? (e.g. pop characters-2 )?

[zooneyl]

Why does "characters.shift( )" have to be put in a variable in order for the log to display it?
It works for me without

Hi Steve, I facing 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. Can you please check.

[CesarJuarezVargas]

If you would only leave wouldn't that leave you with only LUKE to display? It happened to me. I didn't have to create the rem variable.

[CesarJuarezVargas]

What difference would it make if I use as many .pop as needed in order to only display "Luke" versus using .shift once and have it removed from the top of my list (assuming we are working only with the original array from the start)?

[CesarJuarezVargas]

I discovered that if I try .unshift [3], it displays a number 3 instead of "Chewie' as I would have expected. You have to retype the value that was deleted. Any shortcut to retyping?

[persiansayed]

While practicing, I used the shift method to remove the first element in the console.log method and it worked. I am curious why it didn't work in your example.
My code:

let games = [`Assassin's Creed`, `Prince of Persia`, `Far Cry`];
games.push(`Need for Speed`);
console.log(games.shift());

[ralphdeeney]

I love your style. But my question is how can you reverse words with 6 or more letters in a given string after I split to array ? That is 'My second programs code' turn to "My dnoces smargorp". Thank you

[erikaperley]

Hi Steve! Could you name a context where the unshift would be useful (real-world example)?
