Implement TypedArray objects #893
Description
ECMASCript feature
It would be very nice to get TypedArray objects. They are making us fail / ignore many tests in our ECMAScript conformance suite, and they shouldn't be super difficult to implement using our current builtin objects as a template.
You can find the full specification here.
Example code
This code from MDN should give the expected results:
const typedArray1 = new Int8Array(8);
typedArray1[0] = 32;
const typedArray2 = new Int8Array(typedArray1);
typedArray2[1] = 42;
console.log(typedArray1);
// expected output: Int8Array [32, 0, 0, 0, 0, 0, 0, 0]
console.log(typedArray2);
// expected output: Int8Array [32, 42, 0, 0, 0, 0, 0, 0]Implementation tips
To implement these, we should create a new module here called typed_arrays, and a submodule for each variant. You can see an example of a built-in object implementation here.
