JavaScript Bitwise Operators

[@wing3789]

It's truly impressive to be able to explain a concept this complex in such a simple and concise way. Bravo and thank you. I think I understand the basic concept now, but probably wouldn't be able to articulate it half as well if I were to relay the information. Gotta talk it out with my rubber ducky.

[@avtem]

Wow! I've been learning c++ for 2 years, but you explained it so well for me, that now I understand a lot better everything!

[@drcl7429]

since ECMA 6 it is possible to write the binary values directly like how you do in other languages. i.e. assign using: let x = 0b1010101; console.log(x); will output 85

[@codesymphony]

can you convert it back to binary? or at least a string that represents the binary?

[@pipitgusmayanti8342]

@@codesymphony x.toString(2)

@@pipitgusmayanti8342 Thank you.

showing a permissions system as a bitwise example really helped me to see the use cases for this type of work.

[@systemofapwne]

Even though, you speak about how "special" the case is in terms of "when you need it" (and I can't disagree on that), I really also expected negate, XOR and also the bitwise shift operators. Once you started with bitwise operations, it's very common that you also will use the other operators too. In cryptography or bare network commnication, you will stumble upon this pretty fast (except if you use existing libs of course).

[@tonyynot484]

.. then use libs.. why go the hard way when there's an easy way?

[@toddroberts7886]

This wasn't confusing at all actually, thanks to you.

[@WebSurfingIsMyPastime]

Exactly what I was looking for, literally had this same issue to resolve for work, had not been introduced to bitwise permissions prior to my current task.

[@placeholder_name321]

the LEAST confusing I've ever watched on binary code and bitwise operators. Thank you!!

[@nchecker00]

Thanks! I didn't even notice how the vid come to end. Great job

[@kaylanwalker5022]

Thanks, needed this today to decode googles encoded polyline response when using the directions api with fetch.

[@johnbaxter7582]

Mosh : "bitwise operators don't have much uses" Me : "Are you sure about that?"

[@TheCodingOdyssey]

this was really interesting. I'll go ahead and try this right now so I can better add it to my long term memory :D

[@matt-g-recovers]

Thank the gods who power my computer for Mosh...I am almost there. I have been all over asking: Yes, properly confusing but WHY would we bother ? and WHY shift them(java) with any certainty of what is happening!??

[@grishavasilyan]

I'm trying to understand some part of React core concept and there used that biwise operators. Now I get what it is. Thanks a lot.

[@lancemarchetti8673]

I actually use this technique a lot with CTF obfuscation challenges.

[@thesoftwarecoder1603]

Oh Mosh! You are incredible! Thank you so much! You saved my Day! Great explanation capabilities, easy and useful! Go ahead! Thanks a lot!

[@bijay7]

This was really good. Your explanations are very crisp and to the point Mosh 👏🏽

[@mawesome4ever]

Wow, this is exactly what i was looking for! Thank you! I wanted to make a permissions system similar to Discord and you gave me just the perfect example, wow!

[@crcreatives3298]

i am from india your explanatyoin is so amazing

[@yatnoktse6854]

clear enough to learn bitwise, thanks.

[@matthewblasco4720]

Your explanation is so good. So helpfullllll aaaaa

[@danmiller7709]

Great explanation! Just seems like an overly complicated validation system. But I'm sure that's selling it short. Thanks Mosh!

[@arthursvpb]

This explanation was outstanding!

[@rotinaindependente]

Please you need to organize a playlist, hehe!

[@yutokirizaki7967]

Thank you now I fully understand it

[@Adarsh-ox3dt]

That's confusing but you makes it easy.

[@RobertoGPuentesDiaz]

Thanks for video. I think same. Permissions is ubique case that use...

[@wiskasIO]

Thank you, very helpful.

[@sumabich721]

Okay this was helpful. I'd love to see some real examples for >> and

[@valeriia869]

Wow! Thanks for the clear explanation!

[@chandrakantht3738]

Awesome tutorial mash. Thanks for videos

[@kedar_bairagi]

you are great teacher. thank you 🙏❤️

[@JD-oc3cd]

Thanks mosh I was looking for this 🙏

[@talk2s5061X]

Thanks mate really took me a while to get there cheers 😅

[@danielhbrito]

Awesome example!

[@nakiyingimiriam2460]

Thank you, i have understood clearly

[@kingzeddicus]

Thanks. This is very informative. I think this is a better approach to some things, definitely very useful.

[@maresolaris]

Great thank you for this great explanation. Excellent work!

[@CryptoJitsu]

Fantastic explanation!!

[@gregattraf]

Very nice explanation :) You have made it make sense!

[@notjasonknott]

Brilliant tutorial, thanks a lot.

[@shamirsas709]

This was awesome. Thank you.

[@azatkadyrov3634]

Wow amazing. It always bothered me not to care about bitwise operators, but your video made very clear how useful they can be !

[@aylictal]

A good use of bitwise operators is for generating voxels, or pixel data for some applications. I am dabbling a bit with mode7 graphics and an example of these two operators can be seen here: codepen.io/simon-kyger/pen/WLaRmj

[@joshbarros1995]

Very confusing but still very cool hehe. Thank you sooo much

[@caiocutrim3596]

I really like that....I think it's simple

[@tomasuhrik1662]

I am 100% going to replace one of my colleague's "logical or" with a "bitwise or" just to see them debug it with popcorn in my hands. I am also 100% excommunicating anyone who ever uses this unironically for any kind of permissioning system.

[@FredoCorleone]

Never used bitwise operator... But it is interesting

[@carlosbenavides670]

Good Stuff. Thanks Sr.

[@RagazzoKZ]

Cool! Thanks!

[@iamdanyaal]

Thank You Sir

[@tomarik]

LeetCode 78 solution #3

[@Meleeman011]

i'm here because of a leetcode challenge lol

[@dexdevlon]

Mosh: Bitwise operators are not common Me seeing them in the wild be like: 😶

[@Kitsune_Dev]

This is great thanks!

[@Hasan-po6ud]

Thanks

[@imdadulzaman3450]

this video went over my head

[@davidyomtobian8505]

great video can you also explain how

[@maxgomes92]

Great video!

[@deltdev4540]

what do you mean " we human " mosh XD.... you superHuman

[@nateo7045]

In the example you gave in the video, is there any reason to ever do that outside of just to learn about bitwise operators lol?

[@pereation599]

Thanks. Top!

[@vincentpena7017]

What vscode theme youre using? So sick! Thanks

[@bismillahithouse]

What software are you using?

[@JT-mr3db]

And just like that, demystified!

[@1421jenny]

Once I pay for this course can I access it any time ? Is this a lifetime access course @mosh

[@umairashraf3130]

Good introduction, but why you need decimal at one place and binary at other?

[@arsfreelance]

because bitwise operate at binary numbers level.

[@danialothman]

i was so sure i am never gonna use bit operations, then I got involved in IoT and hardware. RIP

[@AruljothySundramoorthy]

Awesome

[@jpmourag2272]

what's your VSCode theme?

[@NphiniT]

Oh so it's just Logic from mathematics. Gotchya

[@MathewAlex-hc4bf]

But javascript works on the 32 bit interger binary representation of the numbers right . This is 8 bit representation . This is wrong right? Is there anyone who can help me ?

[@fulanipride5529]

Honestly I don't wanna say this but I don't understand. BTW I guess u said they're not that important right...

[@SuperIL12]

you should explain properly, explain the mathematics, how you convert from base 2 to base 10, and where are the other bitwise operators? The example was simple an probably fun for some, but confusing while you were building it up. For a 10 min video, it was decent. The main point of the video, explaining the 2 operators, was a succes, but you could've done more.

[@ohmegatech666]

Rhetoric like this gives web developers a bad name. This stuff isn't obscure technical junk, it's the basic foundations of programming. Saying that it doesn't have practical value is crazy. Sure some front-end only web devs might not be using bitwise operators in their code every day but they damn well better know what they do, and full stack developers are definitely going to use them regularly

[@coldcoder23]

I don't think that I will use this but anyways :;))

[@ShackWrong]

fuggedaboutit...

[@Aswodel]

CS50 week 4 problem set uses bitwise operators and doesn't really explain it well enough to understand it.

[@raachmhamed2233]

hello sir are you algerian ? please #Programming_with_Mosh
