C 101

Notes & playground for JS kiddies such as myself

Quick link to Mr. Srinivas's lessons about C. I can't thank this man enough for his awesome pedagogy and the fact he let it be free for everyone.

Compile into bin (executable)

I) sudo apt-get install gcc build-essential manpages-dev
II) Write a foo.c file
III) Then in terminal : gcc -Wall foo.c -o foo (2)
IV) Run executable in terminal: ./foo

Compile into WASM

I) sudo apt-get install python2.7 cmake default-jre git-core
II) Get emsdk
III) Put this in your ~/.bashrc: source $HOME/emsdk/emsdk_env.sh &> /dev/null
IV) Return to the path of your foo.c
V) emcc foo.c -s WASM=1 -o foo.html (1)
VI) Example incoming

Awesome resource about awesome resources

WASM looks awesome but C makes me wanna cry. What do ?

AssemblyScript is for you: WASM without the hassle of learning a new language

asm.js

Old (out of flavor since WASM) and unrelated, but imo it can still be interesting for JS devs trying to get closer to the machine.
While TypeScript is a superset of JavaScript, asm.js is a subset of it. Basically it works with only three data types:

int: 32 bit integer type
double: 64 bit floating point type
float: 32 bit floating point type

So in the end your application is basically a giant JavaScript array of numbers and pointers to these numbers index. It should give +x% performance over typical, handwritten JS (guess it has to do with Big O and how CPU works, but if you're into this, please check the computer science resource above (& Google) instead of my word).
Afaik esm.js is not meant to be written by hand, but generated by compilers (Emscripten). Pretty much a precursor of WASM, I like what it does to JS, and the fact that it can still be written by hand.
But with the level of masochism involved, sane people better learn C and compile into asm.js (for fun) or WASM (for real).

(1): Assuming you're in correct path. -Wall will display all Warnings, foo.c is target file, -o foo will output an executable named foo
(2): foo.c is target, -s tells emcc to generate LLVM bitcode, WASM=1 WASM=true, -o foo.html output an HTML file named foo (could also be foo.js)
