Notes

Includes support for ArrayBuffer objects.

  1. IE10 (and IE 10&11 mobile) does not support Uint8ClampedArray

Bugs

  • Safari 5.1 does not support Float64Array

  • Firefox 14 and under do not have DataView yet.

  • In versions before Safari 6, Typed Arrays are much slower than normal arrays.

  • ArrayBuffer has no slice method in IE 10.
