I think what you were calling extraction is actually called destructuring (like it's proper term). Nice video, definitely learnt something new
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}
Who gets to decide which is term is proper and which is not?
@@cipherxen2 the language spec?
@@anarchoyeasty3908 language specs are not written in stone, they also change
@@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.
1. Designer Mode 0:47
2. Roll the Dice 1:24
3. Merging Array 2:06
4. Extracting from Objects 3:46
5. Generator Color 5:24
6. Copy to Clipboard 7:54
7. Transitionend 8:47
8. Short is Statements 9:56
9. Console Table 11:28
10. Screen Capture 12:03
#4 is known as "destructuring" & #8 are known as "guard clauses"
#5 either "Generate Color" or "Color Generator", but there's already something in JS called a Generator, and that doesn't have a color
#8 guard/guard statement. that's not a JS specific thing.
@@bansh3ee True it's not JS Specific but it's still called a guard clause.
@@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.
Always amazing to be greeted as "gorgeous" 😅😁
With all due respect, I thought you're already fed up with it. You must be called gorgeous all the time... :$
Damn, people are now hitting on girls on RUclips nowadays. What a time to be alive
@@elfelipe1996 Absolutely not, just stated the obvious!
Yeah, this guy is a smoothie
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. ;)
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.
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.
Gracias querido por estos tips; hace mucho no programaba ni lo más mínimo en js y me voy desactualizando, pero aquí aprendí nuevas funciones y demás
This is really great! Thanks for this content Ed! 🚀
Your tutorials are always so engaging and easy to follow 🔥🔥🔥
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 😀😎
With the first video, the CSS one, you got my like and save, with this second one you got my like and subscribe!
Cool!
Although I knew most of these one-liners. Only DesignMode and transitioned events are new to me.
Thanks for sharing.
That color generator is awesome!! Tyvm!
I've always called the "one line if" a guard statement, or a guard if statement. Helps a ton with nesting.
"guard statement" is a proper term for the thing as well
8. is actually called a Guard Clause, very useful to avoid nested if statements!
Dude. The random hex was super clever. My favorite new trick.
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
The only thing which I didn't know was 5:01, but it's good to revisit things once in a while, great video!
Thanks a lot bro. awaiting for more videos from you.
Thank You Ed This Is Realy Amazing
Hey there, Gorgeous Ed on the internet. I really love these types of "must-know" videos. Keep them coming! 😀
Really coool video 🔥🔥🔥
Cool setup as well 😊
By the way, please tell me the model of your monitor, it looks dope
Very fun video, it brings me joy that I knew almost 5 of them.
Hi ed .
I wont to ask you from were you have learned data structure and algorithm?
Thank you ed for your courses🌺❤️❤️
thank you for this video, you are awesome!!
i love your music taste, super chill
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!
Nice video, I like the way you explain. Nice work dude.
he claims to be using the palenight theme, but here hes using the Community material theme ocean high contrast... you're welcome
Ed called me friend👌🏻 Life complete, haha,
These videos are actually golden, keep it up
You are a developer and a successful youtuber, but from the outlook, you could be an actor too. No joke.
Technically you can do anything in one line in JavaScript xD
Cool! I like the screen capturing
Array.from(new Set([…..])) is much cleaner than what you did and is the preferred way btw
Hey man, you're videos great as always, do you consider making a video about javascript road map?
Very useful thanks for sharing
designMode extremely blows my mind. Great content !
Always good content, you're the best
Ed can u please tell mr what monitor are you using? Looks amazing.
The random color hex thing blew my mind!
`console.table(data)` at 11:45 very useful tip!
Love the new video quality 😍😁
Love your energy 👍
Thank you so much !
Thank you very much!!!
Really nice video, Ed!
That merge one liner is great is for interviews
Grateful for this video 🤝
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.
After CSS one-liners, now this = New Subscriber here :)
The design mode one was very helpful, the rest are also helpful but it's just regular es6 stuff.
I will make a shortcut of this video to my desktop. Thanks Ed.
thanks for the tutorial Ed Helms.
thank you very much 🙌
Very cool)) Thank you)
aspiring fan here... i allready new this, but i kinda forgot the other so thanks for the reminder
this man is pure positive energy, lovely human being :)
What is the lens you used for recording this video?
Very nice vid Ed! 🚀 That monitor at the beginning, is it Dell? Can you tell me the type? 😊 Cheers!
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.
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.
I legit thought this was gonna be a video about Javascript jokes
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!
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
Why is that super important you nerd
This is definitely important, but it's also 2022, there are no excuses to not have an SSL certificate on your website.
It's short just fiery content!!!
Thanks for this hacks 😉
We love you, Ed. Just wanted to let you know that.
JSON.stringify(data,null,2)
Really good video ❤
The designmode one is super helpful while designing sites
who would have thought...
Hello plz I m looking for a function or whatever that can help me find list of printers installed on my machine. Thanks lot for your videos
Hi, how are you? I have a question. How to implement animation in Figma on the web-site? I can't find a solution on the internet
Ur my best teacher 💜
Doesn't generate colors have an issues with missing leading zeroes in numbers less than 0x100000?
I don’t know how many years Ed has been calling me a gorgeous friend on the internet 😂
Awesome! I knew all of them but what was the last one? Didn't know about it
Thanks! By the way, what is theme color name ?
did he just say "g" when going through the hexadecimal characters at 7:20 lmao
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 .
i used the "Custom CSS and JS loader" vs code extension and then custom CSS to color the different elements of vs code :)
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 .
the 70's prono music in the background makes the video
This is a good one.
Could anyone please explain where the duration was set for the button to fade out before being transitioned to a display of none? (Transitionend 8:47) Thankyou
What's you display brand & model?
You remind me of the guy in Camera Conspiracies
For merging arrays, concat is easier to read.
Man transitionend will save me tons of time!!!!
I like your energy, friend
I like the console.table command.
The extraction is very useful for any Async call
The official name is destructuring, just in case you want to look it up
what is your monitor please?
Very good
You're crazy. I love u💚( as instructor)😅💪💪💪
Good Things devEd mawa
What vscode theme are you using in this video?
he claims to be using the palenight theme, but here hes using the Community material theme ocean high contrast... you're welcome
@@Mwtorres89 thanks 🙏🏻
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
Awesome
thsnks
Can somebody tell, what is the name of his Vs Code theme ?
This man a little dr crazy looking . Dude thank you.
Can you make a web3 tutorial?
Beard look great Ed ☺️
2:45 you aren't merging two arrays, what you're doing is concatenation. Merging two arrays is more like a zip operation.
Loop over one and and use the current index to get the corresponding element in the other array, then combine both values as a tuple, or whatever structure you need.
Amazinggggggg 🎉🎉
👍 great content - thanks so much !
👍 no floating presenter head
👍 video and audio quality
👍 larger ide font size
👎 (imho) loud, distracting "music"
