An array of typed arrays to concatenate.
Concatenate an array of typed arrays into a single ArrayBuffer. This is a fast path.
You can do this manually if you'd like, but this function will generally be a little faster.
If you want a Uint8Array instead, consider Buffer.concat.
An ArrayBuffer with the data from all the buffers.
Here is similar code to do it manually, except about 30% slower:
var chunks = [...];
var size = 0;
for (const chunk of chunks) {
size += chunk.byteLength;
}
var buffer = new ArrayBuffer(size);
var view = new Uint8Array(buffer);
var offset = 0;
for (const chunk of chunks) {
view.set(chunk, offset);
offset += chunk.byteLength;
}
return buffer;
This function is faster because it uses uninitialized memory when copying. Since the entire length of the buffer is known, it is safe to use uninitialized memory.
