How can I merge TypedArrays in JavaScript?

Question

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.:

var a

Use the set method. But note, that you now need twice the memory!

var a = new Int8Array( [ 1, 2, 3 ] );
var b = new Int8Array( [ 4, 5, 6 ] );

var c = new Int8Array(a.length + b.length);
c.set(a);
c.set(b, a.length);

console.log(a);
console.log(b);
console.log(c);
