Internationalization I18n

Covers the full stack of making your app work in multiple languages, from setting up i18next or React-Intl to handling the tricky stuff like pluralization rules that vary by language, RTL layouts for Arabic and Hebrew, and locale-aware formatting for dates and currencies. Includes references for both frontend (JavaScript/TypeScript) and backend (Python gettext) approaches, plus practical guides on translation workflows and locale detection. The best practices are solid reminders about text expansion and why you shouldn't concatenate translated strings. If you're building anything that needs to support international users beyond just swapping out a few English strings, this gives you the roadmap and gotchas to avoid.
