Building applications with the MERN stack (MongoDB, Express.js, React, and Node.js) is exciting, but let’s be real—it can get a bit overwhelming sometimes. The good news? There are tons of libraries and packages that can make your life a whole lot easier.
React.js is a fantastic tool for building fast, interactive, and user-friendly web applications. But let’s be honest—when it comes to getting those shiny new apps noticed by Google, Bing, and other search engines, React has a bit of a reputation problem. Why? It’s all about SEO (Search Engine Optimization). Since React relies on client-side rendering, it often struggles to serve up content in a way that search engines can easily digest. And if Google can’t see your content, it can’t rank it, which means fewer visitors and less business.
State management in React is crucial for maintaining and updating the data that drives your application’s UI. As your application grows, managing state can become increasingly complex, leading to potential bugs, performance issues, and code that is difficult to maintain.
Callback hell occurs when multiple nested callbacks are used in asynchronous programming, making the code difficult to read, maintain, and debug.
CORS is a security feature implemented by web browsers to prevent web pages from making requests to a different domain than the one that served the web page. While this security feature is essential for protecting users, it can cause issues when you need to make requests to an API hosted on a different domain.
