Javascript Programming Tutorials, Guides & Best Practices

Create pages/Home.js:

import { useTranslation } from 'react-i18next';

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

Set up your translation files, detect user language, and switch languages dynamically using:

i18n.changeLanguage('ar');

Update i18n.js:

import ICU from 'i18next-icu';

i18n
  .use(ICU) // Enables datetime and currency formatting
  .use(LanguageDetector)
  .use(initReactI18next)
  .init({
    ...
    interpolation: {
      format: (value, format, lng) => {
        if (format === 'datetime') {
          return new Intl.DateTimeFormat(lng).format(value);
        }
        if (format === 'currency') {
          return new Intl.NumberFormat(lng, {
            style: 'currency',
            currency: lng === 'fr' ? 'EUR' : 'USD',
          }).format(value);
        }
        return value;
      },
    }
  });

npm init vue@latest
cd analytics-app
npm install

Install dependencies for Webpack configuration:

import create from 'zustand';
import { devtools } from 'zustand/middleware';

const useStore = create(devtools((set) => ({
  count: 0,
  increase: () => set((state) => ({ count: state.count + 1 })),
})));

You can persist state to localStorage or sessionStorage:
