TypedArr (TC05)

   1:  const uint8Array = new Uint8Array([0, 128, 255]);
   2:  const int16Array = new Int16Array(uint8Array); // Create a new view
   3:  
   4:  
   5:  console.log(uint8Array) // Output: Uint8Array(3) [ 0, 128, 255 ]
   6:  console.log(int16Array); // Output: Int16Array(3) [ 0, 128, 255 ], values are reinterpreted.
   7:  
   8:  const float32Array = new Float32Array(uint8Array);
   9:  console.log(float32Array); // Output: Float32Array(3) [ 0, 128, 255 ]
  10:  
  11:  const arrBuf = new ArrayBuffer(12);
  12:  const x = new Uint8Array(arrBuf);
  13:  x[0] = 100;
  14:  x[1] = 101;
  15:  x[2] = 102;
  16:  console.log(x) // Output: Uint8Array(12) [ 100, 101, 102, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
  17:  
  18:  const y = new Int16Array(arrBuf);
  19:  console.log(y) // Output: Int16Array(6) [ 25700, 0, 0, 0, 0, 0 ]
  20:  
  21:  const z = new Int32Array(arrBuf);
  22:  console.log(z) //Output: Int32Array(3) [ 673059850, 0, 0 ]



Converting Between Typed Arrays:

Uint8Array(3) [ 0, 128, 255 ]
Int16Array(3) [ 0, 128, 255 ]
Float32Array(3) [ 0, 128, 255 ]
Uint8Array(12) [
  100, 101, 102, 0, 0,
    0,   0,   0, 0, 0,
    0,   0
]
Int16Array(6) [ 25956, 102, 0, 0, 0, 0 ]
Int32Array(3) [ 6710628, 0, 0 ]
