<section id="description">
Functional programming is a style of programming where solutions are simple, isolated functions, without any side effects outside of the function scope.<code>INPUT -> PROCESS -> OUTPUT</code>
Functional programming is about:
1) Isolated functions - there is no dependence on the state of the program, which includes global variables that are subject to change
2) Pure functions - the same input always gives the same output
3) Functions with limited side effects - any changes, or mutations, to the state of the program outside the function are carefully controlled</section>
