[Question] Have you considered representing the opcode output as an ES6 Typed Array?

[AKST]

Apologises if this is the wrong place to ask this, but I watched the awesome talk by Godfrey & Yehuda on the upcoming changes to glimmer, and I couldn't help but notice you guys were representing your op code as a series of arrays and strings. I had a further look at the source and (I think) that is the case. Have you considered outputting the opcode in the form of a typed array?

Most of the performance boosts would come from the fact Typed arrays have a contingent memory layout, which could likely lower memory usage, provide an additional execution boosts, and could decrease the overall network footprint. The main drawback I can think of is the lack of IE 9/8, or Opera mini support.

Thoughts?

@AKST i think the issue with your suggestion is that the wire format is JSON and if I understand correctly typed arrays are a JS feature, but not supported by JSON

[AKST]

Not sure why I specified typed arrays originally, but you are correct. However looking back on the initial issue I made I probably meant to suggestion the templates could be compiled down to a binary format verses a JSON format.

Like it would be significantly more complex to implement, but the performance increase would probably negate that. Idk, I might close this ticket though because this type of implementation probably does align with the future of ember.

@AKST this work will be of interest to you:

• Move to Binary VM #376
• Integrate Glimmer Macros For Binary VM emberjs/ember.js#14781

This is probably what i had in mind when I posted the issue, cheers!
