Let’s Build an Age Calculator with React Hooks in Nextjs

To build an Age Calculator with React Hooks in Next.js, first, you need to set up the development environment using Create React App.
Add Tailwind CSS for styling and import the useState hook from React to manage the application's state.
Create a function called calculateAge that takes the birth date as an argument and returns the calculated age.
Design a basic user interface with an input field for birth date, a button to trigger the age calculation, and a display area for the calculated age.

Changing Browser Locale in Selenium Automated Tests with examples.

To change the browser locale in Selenium automated tests, one method is to set up arguments to Chrome startup configurations before launching the web driver.
Another method involves using the CDP (Chrome DevTools Protocol) commands along with Selenide methods to programmatically override the browser's locale.
However, there seems to be an issue with ChromeDriver 114 and previous versions where overriding the browser's locale does not work.
This issue has been raised in the Chromium community, but no solution or results have been provided yet.

Fixing npm Errors When Creating React Apps with npx create-react-app

Issues may arise while using npx create-react-app to initialize a React project due to npm errors or conflicting versions.
Efficient component design is crucial for building performant React applications. Opt for smaller, reusable components and utilize React's built-in features like React.memo and useMemo hook.
React provides tools like React.memo and useMemo to improve performance by reducing unnecessary re-renders.
For complex applications, dedicated state management libraries like Redux, Zustand, or Jotai should be considered based on the application's size and complexity.

Using retro designs from 90s websites to inspire modern UX

The 90s witnessed a significant shift in computers becoming personal entertainment devices and tools for self-expression, which led to an experimental aesthetic in web design.
Designers in the 90s created unique designs marked by a mix of colors, fonts, animations, textures, and other technical aspects, which has inspired modern UX in various ways.
Despite its primitive look, the 90s aesthetic has influenced contemporary design, as retro website designs evoke nostalgia and appeal to audiences who remember the era's experimentation and distinct digital aesthetic.
Key characteristics of 90s website design include overloaded visuals, animated GIFs, color palettes, typography, skeuomorphism, textures, and the philosophy of 'more is better.'
Lessons from notable 90s websites, such as Geocities, can help identify design approaches that emphasize individuality, simplicity, and avoiding clutter.
Retro elements in UX offer an opportunity to balance creativity with usability, evoke a sense of nostalgia, and stand out from minimalist templates.
Modern UX design should always prioritize user experience, recognize design history, and leverage past designs while applying design fundamentals and updating outdated features.

3 Myths, 3 Facts, and 3 Strategies to Scale Node.js Apps

Node.js is designed to scale, but its performance at scale depends heavily on application architecture, optimizations, and your approach to managing system resources.
Node.js is built on an event-driven, non-blocking I/O model that actually allows it to manage thousands of concurrent connections with ease.
Node.js delivers performance comparable to compiled languages for many use cases because of Google’s V8 JavaScript engine, which compiles JavaScript into optimized machine code.
Scaling Node.js is not easy and requires thoughtful planning and the right architecture.
Node.js’ single-threaded, event-driven model is great for I/O tasks but when it comes to CPU-intensive operations, this same model can become a bottleneck.
Memory management is critical for growing Node.js applications.
Clustering is necessary to take advantage of all available CPU cores for high-traffic Node.js apps.
Load balancing, caching, and database optimization are three strategies to scale Node.js.
Many large platforms like Netflix, LinkedIn, Uber, and Walmart already rely on Node.js to handle millions of users.
With the right strategies, Node.js can handle the pressure and truly create fast, dependable, and scalable applications.
