Python: How to Reverse a String

Create pages/Home.js:

import { useTranslation } from 'react-i18next';

export default function Home() {
  const { t } = useTranslation();
  return (
    <div>
      <h1>{t('title')}</h1>
    </div>
  );
}

• 🌍 Wider reach
• 📈 Better SEO
• 🤝 User trust and satisfaction
• 🏆 Competitive advantage

• Integrate with Next.js for SSR & SEO boost
• Enable dynamic locale loading for performance
• Add translation CMS support (Locize, Phrase)

Create folder structure:

/src
  /locales
    en.json
    fr.json

cd app-shell
npx webpack serve

const count = useStore((state) => state.count);

By selecting only the necessary state slices, you can optimize component rendering and improve performance.

Implementing these practices ensures that only components dependent on specific context values re-render when those values change.([Medium][7])

React Developer Tools provides a Profiler tab to analyze component rendering behavior. Use it to identify components that re-render frequently and assess the impact of optimization strategies.([tenxdeveloper.com][8])

Comparison and logical operators allow you to compare values and perform logical operations. They are fundamental for decision-making in JavaScript, such as in if statements and loops.

Comparison operators compare two values and return a boolean (true or false).

     let sum = 10 + 5; // 15

• Subtracts the second number from the first.
• Example:

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

  let fruits = ["apple", "banana", "cherry"];

  let isLoggedIn = true;
  let hasAccess = false;
  console.log(isLoggedIn && hasAccess); // false

A variable that has been declared but not assigned a value is undefined.

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

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

• Example:

     console.log("My name is Alice.");

     > console.log("Hello, Node.js!");
     Hello, Node.js!

• Create a new file named example.js and add the following code:

     5 + 10 * 2;

• Select an element on the webpage and access it in the console using $0:

• Go to File > Preferences > Settings and search for "Auto Save."
• Set it to afterDelay for smoother development.

• Open VS Code and create a file with the .js extension (e.g., test.js).

• Frameworks like Electron allow creating cross-platform desktop apps.
• Example: Visual Studio Code.

• JavaScript is used in IoT devices for controlling hardware and sensors.
• Example: Node.js-based IoT applications.

In this tutorial, we will walk you through building a fully functional Chrome extension that automates tweets on X (formerly Twitter). This extension allows you to create tweets from a pre-defined list and post them automatically on your X account at regular intervals.

We'll break the tutorial into clear, manageable steps so even if you're a beginner, you can follow along.

import { createSelector } from 'reselect';

export const selectUsers = (state) => state.users.entities;

export const selectActiveUsers = createSelector(
  [selectUsers],
  (users) => users.filter((user) => user.isActive)
);

Use these selectors in your component:
