Thomas Weber e8d1e449a9 execute: Optimize listIndex 2020-09-09 22:03:56 -05:00
Thomas Weber 80e0bccabc js: Use bitwise | 0 instead of Math.floor in list.get optimization 
This is a lot more significant than I imagined it would be.
 2020-09-09 22:03:24 -05:00
Thomas Weber 94f09e10b2 js+execute: Remove listGetFast 
The ?? operator is used instead.
Older browsers now simply won't get this optimization.

Thomas Weber 7b739fc7f9 js: Nuke VariableInput and Frame 2020-08-31 21:20:59 -05:00
Thomas Weber a4f096ae8d js: remove inheritValues (#15) 
The caching of VariableInputs was causing one stack to incorrectly affect another stack.
The fix is to remove inheritValues entirely until a better method of doing this can be found.
A third phase of compilation is the most likely thing.

Thomas Weber 8906347ed6 Refactor script compiling 
This moves most of JSCompiler into compile, where it should be anyways.
This will make more sense in the future if there is ever more than 1 code generator (asm.js? wasm? glsl? who knows)
