Imagine you have two computers that need to talk to each other, but they speak different languages. Middleware steps in to help them communicate effectively. It acts like a translator to ensure information flows between these computers.
Node web framework
When people say Express is “unopinionated,” it means that the Express.js web application framework for Node.js doesn’t enforce strict conventions or coding styles on developers. It provides flexibility, allowing developers to make their own choices about how to structure and design their web applications, unlike opinionated frameworks like Ruby on Rails or Django, which come with predefined conventions and best practices.
A module is a self-contained, reusable unit of code that encapsulates a specific functionality or a set of related functions. Modules help break down a larger program into smaller, manageable components, making the codebase more organized and maintainable.

To install the “jshint” library/package into your Node.js project, you can use the “npm install jshint” npm command in your project’s root directory.
Tests are important because they guarantee the quality and safety of our creations.Tests are like quality checks for things we create, such as computer programs or cars. They help ensure that what we make works correctly and is safe to use by catching problems before they become big issues.
Improved Quality, Bug Detection/ Prevention, Maintainability. Additionally, testing can also lead to increased developer productivity, better collaboration among team members, and enhanced customer satisfaction, as it helps deliver software that is more reliable and meets user expectations.
Individual pitfalls in writing tests include creating overly complex tests and failing to achieve comprehensive test coverage. Team pitfalls involve inconsistent testing practices among team members and neglecting the maintenance of tests over time.
Improved Code Quality, Early Issue Detection, Faster Development and Deployment
the difference is in the final step of the process. In CD, code changes are automatically prepared for production but require a manual decision to release them. In Continuous Deployment, there is no manual intervention, and code changes are automatically deployed to production as soon as they pass all tests and checks. =
GitHub is like the engine that powers collaboration and teamwork in software development. It keeps track of changes, helps teams work together, and ensures that the software is high-quality and reliable before it’s released to the public. It’s a critical tool that makes modern software development possible.
The backend isn’t discussed nearly as often as frontend, so I am looking forward to solidify my understanding of what exactly is needed.
