Your tutorial broke through my mental block on Bitwise Operators. Thank you for making it so easy to understand.
You are always the best. Thank you for zooming your screen to aid your viewers in seeing the code better.
Great video! you simplified what MDN Docs had me scratching my head at. Earned a subscriber.
Great stuff.. One little note: "Binary operator" refers to arity - that it uses 2 operands not that the operands are in binary. There are also ternary (?:) and unary operators (++) . The operators we're talking about are logical / Boolean operators - they're often used interchangeably, but some materials make the distinction
Man, THANK YOU VERY MUCH! I finally understood this, dude! I'm reading the book Cracking the Coding Interview and one problem there has two different implementations. One of them has bitwise operation. You freaking saved me!
thank you for this tutorial, I have learned something !!!
thank you so much. this is a well detailed video
thank you for this!
thank you! thank you! thanks a million.
Great explanation!!
Awesome as always 👌👌👌
THANKS!
Well explained
Thanks Sir😀 for the video
tbh sir i love the way you explain it to me ... i wish you would share your knowledge to us
Thanks a ton
I really appreciate you. Thanks a lot
You are very welcome! Thanks for watching!
thanks
would have been nice to see some applications as well, if one just sees how something works, but no real world application, one is bound to forget it. Thanks for the video though!
excellent explanation of the topic
Glad it was helpful Ruchika! Thanks for watching!
It's very useful
Glad you think so!
The first application that came to my mind was checking if a number is odd or even with:
`let isOdd = number & 1 ? true : false;`
translation: if (number & 1) is true (equals 1), then isOdd is an odd number, or it is an even number !!!
That is a very simple and elegant example of how to use bit-wise operators in a real application. Thanks for sharing!
thanks for your video. create a video about how to create mini project , with good coding style with vue js
concept is clear no doubt, can you please give a real world example or any algorithm where we can use it.
Thanks
Arjun , here is a huge list of algorithms that you can solve using bitwise operators. www.geeksforgeeks.org/bitwise-algorithms/
alright techsith, I get it and I did learn something new, thank you. it reminds me of some Logic problems I've looked at before... but I can't help to wonder (as a new programmer) why? why so much sweet number logic? Wasn't binary enough in the first place? also, I'll gladly translate your video to spanish if nobody has already.
Hi! please help me to convert this array var [-1, 0, 12, 5, -23] to [1, 0, -12, -5, 23] without using loop.
i am stuck on server-side rendering can anyone help me?
Can u pls give more real world examples in javascript for this
The best example is to tell an odd or even number :
getEvenOrOddNumber(68) // output : 68 is Even number
getEvenOrOddNumber(73) // output : 73 is Odd number
function getEvenOrOddNumber(num) {
let temp = num & 1 ? true : false
if (temp) console.log(`${num} is Odd number`)
if (!temp) console.log(`${num} is Even number`)
}
Stephen, thanks for sharing , this is a great example.
@@Techsithtube I always use these whenever making a card or board game. You can have the first for bits represent the value and the last 4 the suit. They are really useful whenever you want to encode anything. It is actually faster and way easier to manipulate then making any type of object or something similar a shame people really underestimate just how useful and imo better using bitwise operators are to encode things like cards, gameboards, and many other things.
Other than video tutorials what will be the best websites to learn javascript and new features ofJavascript?
mozilla has a great archive called mdn , it can get bit complex but its a great place to learn js.
*If you are a competitive programmer then you will know about this*
I've seen leetcode solutions where they did some kind of black magic using |
SIr - Please post on GraphQL if possible
Ganesh, Yes I am actually focused on graphQL recently. Will creating tutorials on it soon. Thanks for the suggestion.
left shift And Right shift
Lol. You could have put in the correction earlier. I was staring at the '&' and trying to see how is that different from the AND operator '&'
YQ, after I edited the video I realize the mistake, I am glad that I caught it while reviewing it . I hope It was clear after the correction. sorry about that.
@@Techsithtube that is alright. I just had a good laugh
The tons of application of this complicated subject is left untold. Will not bother learning bitwise operators. On interview will say it's out of scope of real world application and ask to explaine one if interviewer will dissagree.
Very basic tutorial, not mentioned the real use cases of these.
