Check the Endianness of the System

Little-endian


    Little-endian: Most modern systems (e.g., x86, x64, ARM) use little-endian architecture. In little-endian, the least significant byte (LSB) is stored at the lowest memory address.
    Big-endian: Some older systems (e.g., PowerPC, SPARC) use big-endian architecture. In big-endian, the most significant byte (MSB) is stored at the lowest memory address.

    The DataView API allows you to explicitly specify the endianness when reading or writing multi-byte values. By default, it uses the platform's native endianness, but you can override this behavior.
