I\'d like to merge multiple arraybuffers to create a Blob. however, as you know, TypedArray dosen\'t have \"push\" or useful methods...

E.g.:

Answer 1

As a one-liner, which will take an arbitrary number of arrays (myArrays here) and of mixed types so long as the result type takes them all (Int8Array here):

let combined = Int8Array.from(Array.prototype.concat(...myArrays.map(a => Array.from(a))));
