Implementing authentication for a web application using Node.js typically involves several steps. “Token-based authentication” is a common approach for securing web applications. It involves generating and validating tokens (usually JSON Web Tokens, JWTs) to authenticate users. Here’s how you can implement token-based authentication in a Node.js web application with an example and coding sample:

The event loop is a fundamental concept in JavaScript that enables asynchronous operations, allowing the single-threaded JavaScript engine to handle multiple tasks efficiently. It works by continuously monitoring the call stack and the task queue.
