    const buffer3 = new ArrayBuffer(20);
    const buffer4 = new ArrayBuffer(22);

    const C = new Uint16Array(buffer3);
    const D = new Uint16Array(buffer4);
    const E = new Uint16Array(buffer5);
  
    // Getting the length of the arrayBuffer
    document.write(A.byteLength +"<br>");
    document.write(B.byteLength +"<br>");
    document.write(C.byteLength +"<br>");
    document.write(D.byteLength +"<br>");
