File IO & Modules

create a module that can read a file and display its contents

everything you declare in your file is private. you need to explicitly export by

module.exports.myfunc = myfunc

our public API is module.exports

we can replace this object or add to it

  function say(filename) {
    return fs.readFileSync(filename);
}

var fs = require("fs");

module.exports.say = say;

in a command line tool blocking is not a big issue you can use synchronous file reading (fs.readFileSync)

the say function will return something like this: <Buffer 48 65 6c 6c 6f 20 57 6f 72 6c 64 0a>

everything is done in array string (especially in streams)

you need to call toString() on your data
