Introduction

What is emscripten
emscripten is:
Emscripten is an LLVM to JavaScript compiler. It takes LLVM bitcode, also
called LLVM IR (which can be generated from C/C++ using Clang, or any other
language that can be converted into LLVM bitcode) and compiles that into
JavaScript, which can be run on the web (or anywhere else JavaScript can run).

- Compile C and C++ code into JavaScript and run that on the web

to JavaScript and interpreting code in that on the web
