binarySlice

binarySlice(binary, start, end) → binary · Binary

Extract a subsequence of bytes from binary data.

• binary (required): source binary

• start (required): start byte offset (0-based)

• end (required): end byte offset (exclusive)

let data = toBinary("Hello World", "UTF-8")
{
  first5: binaryToString(binarySlice(data, 0, 5), "UTF-8"),
  rest: binaryToString(binarySlice(data, 6, 11), "UTF-8")
}
// Output: {"first5": "Hello", "rest": "World"}
