JS Bitwise Operators and Binary Numbers

[@RedEyedJedi]

You seem to be the absolute master of zero dislikes. I watch a lot of tutorials on JavaScript from all sorts of amazing people but out of all of them you definitely get the least amount of dislikes because of how clear and concise your tutorials are. Top notch job Steve, thank you so much for the work and effort you put into every one of your videos. I always let your adverts run just so you get paid.

Thanks. Appreciate that. Also appreciate any sharing of the videos that you do.

[@benronkin4299]

Very helpful. I finally understand JavaScript bitwise operations and their applications. Thank you!

[@rotrose7531]

I have to add that the latter part is significantly great, several years ago I tried and failed to automate background color based on some contrast on the main element. With teachings in this lecture, it seems the work can be done. Thank you.

By the way the code you were looking for is (2).toString(2);

[@adicide9070]

explain, please, what wrapping the literal in parens does in terms of js syntax--

[@KL4NNNN]

Wonderful explanation. Totally opened my mind on binary numbers which I always kept myself far away from.

[@galex23032]

Once more Proessor Steve, your explanations are straight to the point and always very helpful....thanks a million

[@rotrose7531]

Thank you for this nice tutorials, this opens me another door to use bizwise operator which I possibly would have never known if not for these explanations.

[@eminqasimov3398]

Tricky way. I learnt from you, let log =console.log. 😄😄😄 So simple,

[@pauloheres]

amazing video. really really awesome! Thanks

[@darkwarrior-3000]

great video steve. wow Bitwise can be usefull :D thumbs up

[@annafalvello8138]

thank you for this video!

[@chesterxp508]

Another very cool tutorial !!!

[@matheusbalao2654]

Awesome tutorial, ty

[@ciprianparaschiv7591]

Just wow.

[@eminqasimov3398]

2..toString(2) add two dots because toString assumes that it is a float number.

[@pashabiceps95]

the space will do the trick: 2 .toString(2);

@Steve Griffith nice video thanks, do you know how to code 2's complement in hexadecimal ? by using javascript ? Thank You

[@SteveGriffith-Prof3ssorSt3v3]

The two's complement is calculated by inverting the digits and adding one. So, to invert the bits, use the Bitwise NOT operator ~ To add one we can use the Mathematical + operator. Then use the toString( ) method with the base set to 16. let num = 45; num = ~num; num += 1; let hex = num.toString(16);
