make a round of performance tuning #538
Description
There's things we can optimize, like preventing new variable creations, using typeof instead of instanceof, etc.
F.e. here's a test that shows instanceof being slower than typeof:

These benchmarks useless unless you have very low-end device, in 2020 thinking about
msisn't good idea, but i may be wrong.On my notebook with 2-core T2060 with 64Mb GPU memory - yes, it's matters, but gives at least 30FPS on some complex animations
Now even phones even powerful than my old notebook, gives at least 45-50FPS which is enough.
Microbenchmarks isn't good + there not a lot of developers which can spent their time to improve performance
This comment is just my thought, sorry if i'm wrong

Where it really matters is when animating a high number of things. Even if we can only improve performance by, say, 25%, then that's awesome because it means we can animated 2500 objects instead of 2000 (for example). The more performance, the better.
Some people really do care about it, especially if they are making dynamic experiences like first person shooters or similar.
But for the vast majority of use cases (for example, any website with an animation here or there) it probably does not matter.
It's similar to React vs Backbone.js: sure, React is faster, but honestly for the majority of use cases Backbone.js with string-based Handlebars templating is perfectly fine and achieves the same thing (however you will definitely not make a performant first person shooter with it).

Yes, you right. I understand you. Thanks for reply.
I really cared about performance always until got job, i learned on job on company: don’t waste time on not important things, so i just said my thought

Hehe, true! Gotta weigh the values. (I'm planning to make a web based first person shooter later, so besides this I'd also like to compile Tween.js to WebAssembly. More on that later!)

Would be great to see tweenjs in WebAssembly :)
Maybe AssemlyScript good choice?

You read my mind! I just merged #544, which converts to TypeScript, and so next steps are to compile the TS with AS.

From @mikebolt in #340,

I will close this. It isn't a concrete idea.
Any time is a good time for optimization.
