How to handle multipart in JavaScript browser?

Question

JavaScript

Hey!
How to process a request with Content-Type: multipart/mixed in a JavaScript browser?
I have already written a parser for such a file.
I store the response body in a Uint8Array. And I'm already working with him. For example, I do a division along the line boundary.
This works very slowly. A file of 20 megabytes can already lead the browser tightly and it happens that everything collapses. We need a different algorithm.
What other ways are there to work with binary data?
In this case, we are interested in searching and breaking into pieces.
