Python: How to Reverse a String

import React from 'react';
import { useTranslation } from 'react-i18next';
import { BrowserRouter, Routes, Route, useNavigate } from 'react-router-dom';
import { routes } from './routes';
import './i18n';

const LanguageSwitcher = () => {
  const { i18n } = useTranslation();
  const navigate = useNavigate();

  const switchLang = (lang) => {
    const currentPath = window.location.pathname;
    const currentPage = currentPath.split('/')[1];

    i18n.changeLanguage(lang).then(() => {
      // Re-map path using new language
      const t = i18n.getFixedT(lang);
      const mappedRoutes = {
        en: { accueil: 'home', 'a-propos': 'about-us' },
        fr: { home: 'accueil', 'about-us': 'a-propos' },
      };

      const newPath = `/${mappedRoutes[lang][currentPage] || ''}`;
      navigate(newPath);
    });
  };

  return (
    <div className="lang-switch">
      <button onClick={() => switchLang('en')}>EN</button>
      <button onClick={() => switchLang('fr')}>FR</button>
    </div>
  );
};

const App = () => {
  const { t } = useTranslation();

  return (
    <BrowserRouter>
      <LanguageSwitcher />
      <Routes>
        {routes(t).map((route, idx) => (
          <Route key={idx} path={route.path} element={route.element} />
        ))}
      </Routes>
    </BrowserRouter>
  );
};

export default App;

Create pages/Home.js:

Globalization in web development is the process of designing and building applications that support multiple languages, regional settings, currencies, and cultural preferences — making your app ready for a global audience.

In 2025, React globalization goes beyond just i18n (internationalization). It includes:

import React from 'react';
import { useTranslation } from 'react-i18next';

const Home = () => {
  const { t, i18n } = useTranslation();

  const changeLanguage = (lng) => {
    i18n.changeLanguage(lng);
  };

  const today = new Date();
  const price = 199.99;

  return (
    <div className="p-4">
      <h1>{t('welcome')}</h1>

      <div className="mt-4">
        <strong>{t('language')}:</strong>
        <button onClick={() => changeLanguage('en')} className="ml-2">EN</button>
        <button onClick={() => changeLanguage('fr')} className="ml-2">FR</button>
      </div>

      <p>{t('date_example', { date: today })}</p>
      <p>{t('price_example', { price })}</p>
    </div>
  );
};

export default Home;

Install i18next-format plugin (optional):

const HtmlWebpackPlugin = require('html-webpack-plugin');
const ModuleFederationPlugin = require('webpack').container.ModuleFederationPlugin;
const path = require('path');

module.exports = {
  mode: 'development',
  devServer: {
    port: 8080,
  },
  entry: './src/bootstrap.js',
  output: {
    publicPath: 'http://localhost:8080/',
  },
  plugins: [
    new ModuleFederationPlugin({
      name: 'app_shell',
      remotes: {
        analytics_app: 'analytics_app@http://localhost:8081/remoteEntry.js',
      },
      shared: require('./package.json').dependencies,
    }),
    new HtmlWebpackPlugin({ template: './public/index.html' }),
  ],
};

Update src/bootstrap.js:
