Learning Functional Programming in Go

Imperative versus declarative programming

Let's look at why the functional style of programming helps us be more productive than the imperative alternative.

"We are not makers of history. We are made by history."

- Martin Luther King, Jr.

Nearly all computer hardware is designed to execute machine code, which is native to the computer, written in the imperative style. The program state is defined by the contents of memory, and the statements are instructions in the machine language where each statement advances the state of computation forward, toward a final outcome. Imperative programs change their state over time, step by step. High-level imperative languages, such as C and Go, use variables and more complex statements, but they still ...
