javascript: converting byte array to string - a comprehensive guide

this tutorial provides a deep dive into converting byte arrays (also known as `uint8array` or `arraybuffer`) to strings in javascript. we'll explore various methods, their pros and cons, and best practices. understanding this conversion is crucial when dealing with binary data received from network requests, file handling, or other low-level operations.

**understanding the basics**

* **byte array (uint8array/arraybuffer):** a byte array is a contiguous memory block containing a sequence of bytes, each representing a number from 0 to 255. in javascript, `uint8array` is the most common way to represent a byte array, providing a typed array view into an `arraybuffer`. `arraybuffer` is the raw memory buffer, while `uint8array` is a *view* that interprets that memory as unsigned 8-bit integers.
* **string:** a string is a sequence of unicode characters. javascript strings are internally represented as utf-16 encoded characters. each character can be represented by one or two 16-bit code units.
* **the conversion challenge:** the core challenge lies in bridging the gap between bytes (numeric representations of data) and characters (symbols with specific meanings). you need to know the *encoding* used to create the byte array to correctly convert it back into a human-readable string. common encodings include utf-8, ascii, latin-1 (iso-8859-1), and utf-16.
