I think what you were calling extraction is actually called destructuring (like it's proper term). Nice video, definitely learnt something new

[@simonjanca]

Yes that's it. Destructuring works for objects attributes OR even positional properties of Array with Const keyword const [first, second] = [1,2] const {f, s} = {f:1, s:2}

[@cipherxen2]

Who gets to decide which is term is proper and which is not?

[@anarchoyeasty3908]

[@anarchoyeasty3908]

@@cipherxen2 ok let me know when it changes from calling it destructuring and this comment thread will become irrelevant. Until such a time as that occurs, the thing is called destructuring.

#4 is known as "destructuring" & #8 are known as "guard clauses"

[@bansh3ee]

#5 either "Generate Color" or "Color Generator", but there's already something in JS called a Generator, and that doesn't have a color

[@bansh3ee]

#8 guard/guard statement. that's not a JS specific thing.

[@ShadowVipers]

@@bansh3ee True it's not JS Specific but it's still called a guard clause.

[@espertalhao041]

​@@ShadowVipers #8 can also be known as an early return, because you return early in your code, while validating the data. It's a little easier to think about it's reason to exist if you call it an early return. Which is what it does: there's no point in going further because you've done all you can up to that point and you have to leave.

[@lainverse]

3:37 I'd like to add that it's worth remembering that using spread operator on arrays have iteration cost attached to it, so the larger the array the slower this works. So, if your code is called many times over it's better to merge arrays in traditional way by pushing elements of one into another. It doesn't matter on small arrays, but on actually large ones (thousands of items) this may cause a noticeable lag. 6:33 6-digit hexadecimal number. In decimal (default representation in console) it can go up to 8 digits. ;)

[@CottidaeSEA]

Another approach is to have a third array that is updated at the same time as the other two. The downside would be that it has to search for the entries, but if using a map, that can be solved through using proper keys.

[@NNNedlog]

Your tutorials are always so engaging and easy to follow 🔥🔥🔥

That color generator is awesome!! Tyvm!

[@alvarocastillocorrea2610]

This is really great! Thanks for this content Ed! 🚀

[@Raju917707]

Thanks a lot bro. awaiting for more videos from you.

[@4Sightfails]

Very fun video, it brings me joy that I knew almost 5 of them.

[@eduardointech]

With the first video, the CSS one, you got my like and save, with this second one you got my like and subscribe!

[@KGmagicjj]

This is a nice list, but I would strongly recommend w this being a teaching channel, to mention the technical name of some of these patterns and operators as you go. Spread operator, object destructuring syntax, guard blocks, etc.

[@EmmaKAlexandra]

I've always called the "one line if" a guard statement, or a guard if statement. Helps a ton with nesting.

[@bansh3ee]

"guard statement" is a proper term for the thing as well

[@bassilmohammad7266]

Hi ed . I wont to ask you from were you have learned data structure and algorithm? Thank you ed for your courses🌺❤️❤️

[@bilalbeny4172]

thank you for this video, you are awesome!!

[@boneykingofsomewhere]

I created a random background-color generator with copy-to-clipboard inside a hex code div (the hex code shows inside the div). Click the button to generate a random colour and if you like it, click the hex field div to copy it. Great little video that has definitely improved my abilities and knowledge, ta Ed 😀😎

[@robertn2997]

Nice video, Blender in combination with Babylon js would be awesome. Not many people make tutorials about Babylon js while it is a great 3D engine for in the browser

[@justusmaier]

8. is actually called a Guard Clause, very useful to avoid nested if statements!

What is the lens you used for recording this video?

[@michaelhofby]

Hey ED :) ! I saw in one of your other video that you had a vs code theme with a gradient up in the title bar in one of your recent videos and i thought it looked SO cool that i figured out how to do it myself :D ... But now you dont have it anymore i see .

[@michaelhofby]

i used the "Custom CSS and JS loader" vs code extension and then custom CSS to color the different elements of vs code :)

[@michaelhofby]

I cant post a screenshot of my vs code .. Cuz youtube deletes the comment but yeah , could be cool to see a video on that .

[@malyarevich]

0:47 Design Mode - awesome feature, I like it! Almost all rest poor, because it is something like part of ECMA standards. Also last one looks impressive. Good job, man, anyway! Thank you!

[@nclsDesign]

9:22 or you just set the visibility to hidden aswell. This will not transition by itself, so you'll still need opacity, but it will change the value once the transition is done.

[@parsonsmarcus]

Setting visibility to hidden will disable pointer events on the element, but other elements in the DOM will be affected by its positioning (unless it's set to an absolute or fixed position). To keep the element on the page, you should set it to "display: none;" so that way it will not affect the layout of other DOM elements and be removed from visibility.

[@bmehder]

This is a good one.

[@streamx2]

what is your monitor please?

The extraction is very useful for any Async call

[@TrevinAvery]

The official name is destructuring, just in case you want to look it up

[@MoheTheDreamy]

I like the console.table command.

[@nunoRRsantos]

[@Azamat78726]

Can somebody tell, what is the name of his Vs Code theme ?

[@trickeddev]

Array.from(new Set([…..])) is much cleaner than what you did and is the preferred way btw

[@ribasenric]

Cool tricks! Fun fact: You can make `const copy = (text) => navigator.clipboard.write(text)` even shorter `const copy = navigator.clipboard.write` no need to wrap in another function that takes text and passes text to it.

[@wfl-junior]

Technically you can do anything in one line in JavaScript xD

[@yoel.taylor]

Super important to note that the Navigator.Clipboard API only works locally or in HTTPS. So if you want to make an insecure HTTP website, copying text won't work!

[@skillzorskillsson8228]

I guess that explains why it was not working for me on codepen. Sure, codepen does use HTTPS but i guess it has something to do with it... Because it is not working at all on codepen

[@hithankyou123]

Why is that super important you nerd

JSON.stringify(data,null,2)

[@eitherplace9844]

Well there is a better option for single line if to only run if not null using ?? operator known as null coalescing operator. However it is best to use for value assignment, similar to ternary operator
