Bash: How to Loop Over Files in a Directory

✅ Translate meta tags using react-helmet or next/head

✅ Enable proper sitemap and routing strategy per locale

• 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:

Use localStorage via i18next-browser-languagedetector:

detection: {
  order: ['localStorage', 'navigator', 'htmlTag'],
  caches: ['localStorage'],
}

With Webpack Module Federation, you can load the Vue-based analytics micro-frontend into the React host — all without bundling it directly.

We’ll build two apps:

With these steps, you've set up a basic state management system using Zustand without the need for additional boilerplate or context providers.

While both Zustand and Redux serve the purpose of state management in React applications, they differ significantly in their approach and complexity.

Example:

import React from 'react';

const Greeting = React.memo(function Greeting({ name }) {
  console.log("Greeting rendered");
  return <h3>Hello{name && ', '}{name}!</h3>;
});

No preview available for this content.

console.log(5 == "5"); // true (type coercion)
console.log(5 === "5"); // false (no type coercion)
console.log(10 > 7); // true
console.log(4 <= 4); // true

Logical operators combine multiple conditions or values.

• Adds two numbers.
• Example:

     let sum = 10 + 5; // 15

  delete person.isStudent;
  console.log(person);

Arrays are ordered collections of elements, which can be of any type.

• Example:

  let user;
  console.log(user); // undefined

     let age = 25;
     age = 26; // Allowed
     console.log(age); // 26

• Used for variables whose value should not change.
• Example:

• The output will be:

     Hello, World!

     node example.js

• Output:

• Use the console like a calculator:

     5 + 10 * 2;

• Open the Extensions view (Ctrl+Shift+X or Cmd+Shift+X on macOS).
• Recommended extensions for JavaScript:
• ESLint: Linting and error-checking.
• Prettier: Code formatting.
• JavaScript (ES6) Code Snippets: Useful code snippets.
• Live Server: Preview your code in the browser.

• Customize the editor's look by choosing a theme:
• Navigate to File > Preferences > Color Theme.
• Popular themes: Dark+, Dracula, Monokai.

• With Node.js, JavaScript powers the back-end to handle databases, APIs, and server logic.
• Examples: REST APIs, real-time collaboration tools like Google Docs.

JavaScript isn't limited to the browser anymore. It's being used in diverse domains:

• Created by Brendan Eich in just 10 days while working at Netscape.
• Originally named Mocha, then renamed LiveScript, and finally JavaScript to ride the popularity wave of Java.

• JavaScript was standardized under the name ECMAScript by ECMA International.
• The first edition of ECMAScript (ES1) laid the foundation for modern JavaScript.

Each file has a specific role:

• manifest.json: Defines the extension's metadata and permissions.
• background.js: Runs in the background to handle tweet automation logic.
• content.js: Interacts with the X website.
• popup.html: The user interface for starting/stopping the automation.
• popup.js: Handles user interactions from the popup.

• Slices, reducers, actions, and thunks in depth.
• How Redux Toolkit simplifies boilerplate code.

• Writing and explaining the usersSlice step by step.
• Using createSlice to manage actions and reducers.
