I have an ArrayBuffer which looks like:
This buffer is placed under variable named myBuffer and what I'm interested in, is to get the Uint8Array from this object.
I tried to loop as:
myBuffer.forEach(function(element) {
console.log(element);
});
and to directly access to the Array as:
console.log(myBuffer['[[Uint8Array]]']);
console.log(myBuffer['Uint8Array']);
but seems none of this is the correct approach
Those pseudo-properties you are seeing are something the developer console is putting there for your benefit. They aren't really there at all, as a property or a symbol (AFAIK), and even if they were it would be non-standard.
You can easily get a Uint8Array view of your buffer the standard way like this though:
new Uint8Array(myBuffer)
You will first need to convert the array buffer into a typed array, then from there you can use the spread operator to create an array
const typedArray = new Uint8Array(myBuffer);
const array = [...typedArray];
Array.from(typedArray), it's more clear about the purpose
new Uint8Array(myBuffer)[[…]](and also__proto__) are just a rendering of internal values by the devtools inspector. They don't actually exist on the object.
