Your tutorial broke through my mental block on Bitwise Operators. Thank you for making it so easy to understand.

@bluescanfly1981 4 года назад

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

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.

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!

The first application that came to my mind was checking if a number is odd or even with: `let isOdd = number & 1 ? true : false;`

@maskman4821 4 года назад

translation: if (number & 1) is true (equals 1), then isOdd is an odd number, or it is an even number !!!

@Techsithtube 4 года назад

That is a very simple and elegant example of how to use bit-wise operators in a real application. Thanks for sharing!

@nadaing 2 года назад

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.

@riyastir 3 года назад

It's very useful

@Techsithtube 3 года назад

Glad you think so!

@TheCodingOdyssey 3 года назад

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!

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/

@Daniel_WR_Hart 3 года назад

I've seen leetcode solutions where they did some kind of black magic using |

@maskman4821 4 года назад

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`) }

@Techsithtube 4 года назад

Stephen, thanks for sharing , this is a great example.

@dtho6231 3 года назад

@@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?

@Techsithtube 4 года назад

mozilla has a great archive called mdn , it can get bit complex but its a great place to learn js.

Ganesh, Yes I am actually focused on graphQL recently. Will creating tutorials on it soon. Thanks for the suggestion.

@yqang2904 4 года назад

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 '&'

@Techsithtube 4 года назад

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.

@olehsavchuk 4 года назад

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.
