|

|
|
* === true Use Uint8Array implementation (fastest)
|
|||
|
|
* === false Use Object implementation (most compatible, even IE6)
|
|||
|
|
*
|
|||
|
|
* Browsers that support typed arrays are IE 10+, Firefox 4+, Chrome 7+, Safari 5.1+,
|
|||
|
|
* Opera 11.6+, iOS 4.2+.
|
|||
|
|
*
|
|||
|
|
* Due to various browser bugs, sometimes the Object implementation will be used even
|
|||
|
|
* when the browser supports typed arrays.
|
|||
|
|
*
|
|||
|
|
* Note:
|
|||
|
|
*
|
|||
|
|
* - Firefox 4-29 lacks support for adding new properties to `Uint8Array` instances,
|
|||
|
|
* See: https://bugzilla.mozilla.org/show_bug.cgi?id=695438.
|
|||
|
|
*
|
|||
|
|
* - Safari 5-7 lacks support for changing the `Object.prototype.constructor` property
|
|||
|
|
* on objects.
|
|||
|
|
*
|
|||
|
|
* - Chrome 9-10 is missing the `TypedArray.prototype.subarray` function.
|
|||
|
|
*
|
|||
|
|
* - IE10 has a broken `TypedArray.prototype.subarray` function which returns arrays of
|
|||
|
|
* incorrect length in some situations.
|
|||
|
|
|
|||
|
|
* We detect these buggy browsers and set `Buffer.TYPED_ARRAY_SUPPORT` to `false` so they
|
|||
|
|
* get the Object implementation, which is slower but behaves correctly.

|

|
|
* The Buffer constructor returns instances of `Uint8Array` that are augmented

* with function properties for all the node `Buffer` API functions. We use
|

|
|
* `Uint8Array` so that square bracket notation works as expected -- it returns

* a single octet.
|

|

*
|

|
|
* By augmenting the instances, we can avoid modifying the `Uint8Array`
|

|
|
* prototype.
