  42. Try WebAssembly

  43. What is WebAssembly? • Source code: What a developer writes.

    • Compiler: An application that turns source code into assembly, bytecode or machine code (what other apps or hardware run). • Assembly: A low-level source-like language specific to a machine or an application. • Bytecode: A low-level binary representation of code that can be run by other applications. • Machine code: A binary representation of code that can be run directly by hardware.
