Methods
(static) bytesFromWord(w, dest, destOffset)
splits a word into two bytes and writes the resulting two bytes into an existing array. The bytes are not returned as an array or object because allocations are expensive.

| Name | Type | Description |
|---|---|---|
w |
Number | the word to split |
dest |
Uint8Array | the destination array |
destOffset |
Number | the offset in the destination array, start of the two bytes |

retn |
Uint8Array | to store the result in, has to be of the same length as parts |
offset |
