A polyfill for ArrayBuffer#dispose

dispose.js

void function () {

if ( 'dispose' in ArrayBuffer.prototype ) return

var blob = new Blob([''], {
    type: 'text/javascript'
})
var url = URL.createObjectURL(blob)
var worker = new Worker(url)
URL.revokeObjectURL(url)

Object.defineProperty(ArrayBuffer.prototype, 'dispose', {
    writable: true,
    enumerable: false,
    value: function () {
        worker.postMessage(this, [this])
    }
})

}()

test.js

var x = new Float32Array(16)
console.log(x.length) // 16
x.buffer.dispose()
console.log(x.length) // 0

Hi!

Nice to hear that it actually does something useful! I'm now quite convinced that something like this shouldn't be standardized, but... Uinfortunately until the garbage collectors become smarter, we need to make our applications smarter to deliver the best performance. :)
