Top 10 Javascript One Liners YOU MUST KNOW!

[@codegenius2932]

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]

@@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.

[@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.

[@trickeddev]

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

[@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

did he just say "g" when going through the hexadecimal characters at 7:20 lmao

[@Pfoffie]

Doesn't generate colors have an issues with missing leading zeroes in numbers less than 0x100000?

[@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 😀😎

[@michastolarczyk7228]

What is the lens you used for recording this video?

[@justusmaier]

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

Cool! Although I knew most of these one-liners. Only DesignMode and transitioned events are new to me. Thanks for sharing.

[@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.

[@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

concat() is another way to merge arrays: arr1.concat(arr2); Retaining only unique values: [...new Set(arr1.concat(arr2))];

[@mihaimanole2643]

6:16 Why do you exclude the pure white? Isn’t it a colour too? Multiply by 0x1000000 to have the chance to get 0xffffff

`console.table(data)` at 11:45 very useful tip!

[@kevinvz5387]

i love your music taste, super chill

[@theyreMineralsMarie]

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.

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.

[@syedabuthahirkaz]

7:50 Code won't work for final zeroes which may be left out in the string conversion, so taking care of these edge cases the correct code is : const generateRandomColor = _ => `#${Math.floor(Math.random() * 0xffffff).toString(16)}`.padEnd(7,'0')

[@kpm25]

@syedabuthahirkaz... Actually, the correct implementation should be: `#${Math.floor(Math.random() * 0xffffff).toString(16).padStart(6, '0')}`; This handles the edge cases of six-digit hexadecimal numbers with leading zeros, such as 00aabb. Using .padEnd(6, '0') would add zeros as trailing zeros, potentially excluding certain numbers from being picked. Conversely, .padEnd(7, '0') would shift all digits one place to the left, resulting in the most significant digit being discarded. This ensures a more accurate and comprehensive random color generation.

[@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

[@migats2160]

7:51 that doesn't work. Because if the first digits are zeros, it will have a different behavior. That's why you need to add 1000000 to it and then replace the first 1 with a hashtag.

[@_invencible_]

who would have thought...

[@indriq78]

Why anonymous fat arrow function as a variable instead of a "normal" function with a name? It's a strange trend nowadays. It makes sense only if 'this' needs to be bound (or maybe to avoid hoisting but in that case there are bigger problems in the code already) in any other cases a normal function is better. easier to read, it has a name => easier to debug, etc.

[@alister_]

Also functions declarations are hoisted. It means you can call them before they are defined to the eyes of the person reading the code. This means you can somewhat handle the order of reading based of what's more relevant to the reader in order to understand or follow the code.

Isn't it better to add .padStart(6, '0') to the fifth oneliner? I mean, if u have generated a number less than 0x100000, it would have less than six digits and you need to add zeros into first registers.
