What a video bro! Can't thank you enough! Thank you so much you made life so much easier!

That's some wonderful content... Want more of that for interview coding rounds and to make our day to day coding life easier as well because these small things can sometimes be a lot tedious for the coders when we can't remember all the things.. So, there should be a Playlist where we can revise these things..

Hey Chris, love these challenges. Really helpful to review on JavaScript concepts before diving into frameworks.

Hey hey Chris 👋
Another good challenge as well.
Another way for "// 9. Alter the original array to only contain the names before "Chris"" is to do : names.length = chrisIndex;
It will automatically reduce the array without creating a new array to remove elements, better faster too :)

Did you know this tip ?

[BaRzOmk]

You dont need the spreed op. in lowercaseNames, map already creates new array

[kashmirtechtv]

Can't we do number 9 with filter and includes?

[JimKernix]

You should also use the spread operator with sort and reverse or else the original array is mutated.

What does this line of code do, what does the = sign which is an assignment operator do here "p.isAwesome = p.favouriteNumbers.length > 3
