Leiningen—A Build Tool in Clojure

With namespaces, we put our functions into files and group related functions together. This helps to keep code separated into units. Consider a situation where utility functions are separated from frontend functions. This helps us navigate code and find functions. We know that frontend functions responsible for creating HTML will not be in a backend namespace responsible for connecting to the database. Build tools serve a different purpose. As the name suggests, these are tools that help us build. With them, we automate the creation of an executable application. An alternative would be to compile all the code ourselves and put it on a server. Even in applications with only a few features, we run the risk of forgetting to compile a namespace. The more namespaces there are and the more complicated an application is, the bigger the risk of making a mistake in manual code compilation. Build tools compile our code and package it into a usable form...
