JavaScript typed arrays — Using views with buffers
First of all, we will need to create a buffer, here with a fixed length of 16-bytes At this point, we have a chunk of memory whose bytes are all pre-initialized to 0.

First of all, we will need to create a buffer, here with a fixed length of 16-bytes
At this point, we have a chunk of memory whose bytes are all pre-initialized to 0. There's not a lot we can do with it, though. For example, we can confirm that the buffer is the right size
Before we can really work with this buffer, we need to create a view. Let's create a view that treats the data in the buffer as an array of 32-bit signed integers
Now we can access the fields in the array just like a normal array
This fills out the 4 entries in the array (4 entries at 4 bytes each makes 16 total bytes) with the values 0, 2, 4, and 6.
