# The Era of Micro Packages

I’ve been planning to write a blog post about this for a long. Building small, focused modules/package means reusability and makes it possible to build larger, more advanced apps.

As stated by [Douglas McIlroy](https://en.wikipedia.org/wiki/Douglas_McIlroy), Unix programs have always been expected to follow the concept of `DOTADIW`.

Some people are obsessed about the `LOC (Lines of Code)`. You shouldn’t care about it. It’s not the key to modular development. All you need to know is how to use the Lego blocks to build a castle. But even Modularity is a powerful concept, but like anything else, it’s not a magic stick.

## One programmer broke the internet

There was a situation in 2016. A man named **Azer Koçulu** broke the internet by removing just a micro-package named `left-pad`. Because many projects use it as a dependency. The impact of these was large as it was being used in numerous very popular projects like *Babel, Atom, React, etc*.
