Notes

  • Steps for JavaScript interpretation:

    1. Source code -> parser -> AST

    2. AST -> interpreter -> bytecode

    3. interpreter -> optimizer -> optimized code

  • V8 interpreter takes profiling data on "hot" functions, optimizes that code

  • SpiderMonkey partially optimizes code and then further optimizes code based on hot code
