Intro to Typed Arrays in JavaScript

Typed Arrays are an efficient way to store arrays of numbers that are of the same type - 8-bit integer, unsigned 16-bit integers, 32-bit floats, etc.
This tutorial explains the basic idea behind them and provides a very basic code sample on how to create one and access it's values.

The code gist includes links to the MDN documentation pages for all the main types and objects discussed.

thanks. first 2 minutes helped me understand the thing I can't realize 2 days

Quality video and crystal clear explanation. Thank you very much.

This was useful for understanding ArrayBuffers, this has been very confusing and it now makes sense to do this rather than to create new Unsigned Integer Arrays from this

Thank you as always, will find a thing where these great ideas can be applied.

Just what I was looking for, thank you!

Thank you so much, this was so helpful! Today I was looking into the Crypto Web API and got confused since I`ve never really worked with typed arrays. This was incredibly helpful!

[nobir]

well explanation and maintained seriality for understanding properly thank you so much

[SubtleD.]

Much thanks for this video. The explanation was easy to understand

[vishalgupta]

very clear explanation, great work thanks !!

[COBHC]

great explanation much better than typical books

Cool video, was playing around a bit and it all made sense :) Was curious what would happen if I tried to assign 1 byte to an array buffer but set the value to int16 which didn't work because it's 2 bytes I guess? Good video!

Thanks for the video I understood everything😀

Difficult topics conveyed in simple flowing terms that make sense. #CodingJesus

Great tutorial, Please i'd like to know more about ArrayBuffer, I got this video searching for "ArrayBuffer" and I really like the video

[calebprenger]

an actual video of how to actually use them would be fantastic.

So to be super clear, Int8Array[x] = y is equivalent to manipulating the DataView corresponding to the TypedArray that the syntax gave me, as in myDataView.set(x) = y (which manipulates myHiddenTypedArray) - is this right?

this is so good and I'd give it 100 likes if I could. 👍👍👍👍👍👍👍👍 Thanks!

nice content, but I really wish the IDE theme was dark

[mahneh]

Great video. But push foreach are not included I think

I was scared of ArrayBuffers, now i'm not :)
