Translating URLs in React improves both UX and SEO, especially in 2025 where Google increasingly favors language-aware URLs over query parameters like ?lang=fr.

• Text translation (i18n)
• Locale-aware formatting (dates, numbers, currencies)
• Cultural UX adaptations (e.g., RTL layouts, color symbolism)
• Language switching + SEO compatibility
• Region-based content rendering (e.g., laws, units, timezones)

In 2025, more users are accessing the web from non-English regions than ever before. Some reasons to globalize your React app:

Create folder structure:

/src
  /locales
    en.json
    fr.json

As web applications grow larger and teams become more distributed, the traditional monolithic frontend architecture becomes harder to scale. Enter micro-frontends — the 2025-ready solution that brings backend microservices thinking to the frontend world.

Micro-frontends allow different teams to work independently on isolated UI components, which are then stitched together at runtime. This enables:

• Simplicity: Create stores using a straightforward API without the need for reducers or action types.
• Performance: Optimized for performance with selective rendering and minimal re-renders.
• Flexibility: Supports custom hooks, middleware, and integration with other libraries.
• No Providers: Unlike Redux, Zustand doesn't require wrapping your app with context providers.

These features make Zustand an attractive choice for developers looking to manage state in a more concise and efficient manner.

import React, { useState, useCallback } from 'react';

function Counter() {
  const [count, setCount] = useState(0);

  const increment = useCallback(() => setCount(c => c + 1), []);
  const decrement = useCallback(() => setCount(c => c - 1), []);

  return (
    <div>
      <button onClick={increment}>+</button>
      <span>{count}</span>
      <button onClick={decrement}>-</button>
    </div>
  );
}

By wrapping increment and decrement with useCallback, their references remain stable across renders, preventing unnecessary re-renders in child components that receive these functions as props.([GeeksforGeeks][2])

Composer is essential for managing PHP dependencies:

Launch apps like this:

• How memory leaks happen.
• How to structure your code to avoid them.
• A design pattern to manage dynamic memory safely (RAII without smart pointers).
• A reusable ScopedPointer class to emulate unique_ptr in old C++.

Consider this code:

This causes both a.data and b.data to point to the same memory. When both destructors run, delete is called twice on the same pointer — undefined behavior!

A deep copy duplicates the actual data pointed to, not just the pointer.

const duration = Date.now() - formStartTime;
if (duration < 3000) {
  return res.status(403).send("Too fast, bot?");
}

Yes, reCAPTCHA is still useful—especially v3, which assigns a score based on user behavior.

You’re no longer blindly relying on a package—you understand and control the system.

Want to extend this?

• Arduino board (e.g., Arduino Uno)
• Breadboard
• LED
• 220Ω resistor
• Jumper wires

• Connect the longer leg (anode) of the LED to digital pin 13.
• Connect the shorter leg (cathode) to one end of the 220Ω resistor.

• Filtering Detections: Display only specific classes (e.g., only people or vehicles).
• Custom UI Elements: Use p5.js to add buttons or controls that modify detection settings in real time.
• Performance Optimization: Experiment with frame rate adjustments or model parameters for faster detection.

Congratulations! You’ve built a real-time object detection web application using TensorFlow.js and p5.js. This project demonstrates how to integrate machine learning models into a browser-based environment and interact with live video feeds. With further experimentation, you can adapt this tutorial to a variety of creative projects, from interactive art installations to practical surveillance tools.

Tauri leverages web technologies to build native desktop applications while offloading critical operations to Rust. Paired with Svelte—a fast, compile-time JavaScript framework—you can create modern apps that are both visually appealing and highly performant. This tutorial will walk you through setting up your development environment, creating a Svelte project, integrating Tauri, and building your first desktop app.

The lexer (or tokenizer) converts a stream of characters into a sequence of tokens. Each token represents a logical unit, such as a number or operator.
