 # Publishing Node.js Modules and Contributing to Open Source
 
-One of the key factors that attributed to the rapid growth of the Node.js module ecosystem is its open-source nature and robust packaging systems (with registry). As of April 2013, JavaScript and Node.js had already surpassed any other language/platform in number of packages contributed per year ([source](http://caines.ca/blog/programming/the-node-js-community-is-quietly-changing-the-face-of-open-source/)): TK

 -   Node.js: *6742 packages per year* (26,966 packages in 4 years)
 
-This year’s (2014) numbers are even higher, and expectations are that, by mid 2014, Node.js will surpass other platforms, in absolute numbers, with Maven and Rubygems being the top dogs ([source](http://modulecounts.com/)).
+This year’s (2018) numbers are even higher with npm having over 620,000 packages. That's more than half a million! As you can see from the chart take from <http://modulecounts.com>, Node's npm surpassed other platforms' package repositories in absolute numbers. Maven Central (Java) and Packagist (PHP) try to catch up but fail miserably. npm and Node are the top dogs.
