javascript - Code works when running node console but not when invoking node <app_name.js> -

i'm using:

npm install babyparse --save 

when invoking

node 

in terminal (os x yosemite), run following commands , see output:

> var baby = require('babyparse'); undefined > var fs_test_data = baby.parsefiles('fs_test.csv'); undefined > var rows = fs_test_data.data; undefined >     rows.foreach(function(element, index, array){ ...         console.log(element); ...         console.log(index); ...     }); [ '3000', '    1000', '    2000', '    30', '    0', '    1', '' ] 0 [ '3000', '    1000', '    2000', '    40', '    0', '    5', '' ] 1 undefined >  

that's great! works!

but....

//test_babyparse.js var baby = require('babyparse'); var fs_test_data = baby.parsefiles('fs_test.csv'); var rows = fs_test_data.data; rows.foreach(function(element, index, array){     console.log(element);     console.log(index); }); 

and running

node test_babyparse.js 

ends showing nothing. why? have io , event loop?

thanks,

edit: i'm using babyparse.js file found on github, not .js file found on npm not have parsefiles function.

phew!

so yes, looked through source of babyparse.js file , noticed 'fs' not defined.

i wrote

fs = require('fs'); 

in test_babyparse.js, believe sets 'fs' in global scope.

it worked!

edit: apparently it's not practice add things global scope that, added

var fs = require('fs'); 

in babyparse.js file.
