Routing 101

React Router is a library that allows you to handle routing within a React application. It provides a way to map URLs to components, so that when a user navigates to a certain URL, the corresponding component will be displayed.

To get started with React Router, you'll first need to install it. You can do this by running the following command in your terminal:

npm install react-router-dom

What is an ESM module?

ESMs (ECMAScript modules) are the official standard format to package JavaScript code for reuse. Modules are defined using import and export statements. 1

Default exports in ESM

The way we export "things" from our libraries impacts the way they can get imported by clients of our libraries.

For example, if we define a module and export cheese from it as the default export:

@Test
public void showProject_shouldReturnAccessDenied_forUnauthenticatedUser() {
    // Given an unauthenticated get project request
    HttpEntity request = unauthenticatedRequest("GET /projects/1");

    // When the request is handled by the application
    ResponseEntity<ErrorResponse> response = handleRequest(request);

    // Then a forbidden response should be returned

Monads for Go Programmers

	import java.util.ArrayList;
	import java.util.List;
	import java.util.Stack;

	public class Node<T> {

	private static final int DEFAULT_MODIFIER = 0;

	private static final int DEFAULT_PRELIM = 0;

	In a world of code, where languages reign,
	There's one that rises above the rest, it's plain,
	A giant among giants, it's called Java,
	A language that's been around, a classic, never to fade away.

	It's strong, it's fast, it's versatile and flexible,
	With a community so vast, it's truly remarkable,
	It's been the backbone of many a great app,
	Making it the king of the programming world, no need to clap.
