DataView [0] itself already has pretty useful methods to work with binary data. To encode/decode strings, use TextEncoder [1]

Both implementations are very optimized and fast. Also DataView offers working with 64-bit values using the new BigInt type [2].

Here [3] a short example on how you can quickly build C-like structures in JavaScript
