What does CommonJs module pattern do?

Answer:

CommonJs module pattern helps to add references to various js libraries as opposed to adding script tags in individual html pages thereby prevents all the UI pages from being getting polluted.The CommonJs module pattern only allowed one module per file - it there by eliminates circular dependencies and helps in finding out the properties regarding the current module.

e.g.

// ourpackage is a dependency needed in the project

var lib = require('ourpackage');

 

// perform some action

function Print(){

    lib.log('it is only a test');

}

 

// export Print to other modules

exports.Print = Print;
