Internationalization with Common Web APIs

Building web applications for a global audience requires more than just translating text. You need to handle diverse date formats, currencies, pluralization rules, and sorting behaviors seamlessly. This course teaches you how to leverage native internationalization (i18n) APIs to build highly adaptable, globally-ready web applications. You will learn to format and present data accurately for any locale using standard, built-in tools. What you'll learn: • Understand core internationalization (i18n) and localization (l10n) terminology. • Format dates, times, and relative time strings natively using the built-in Intl API. • Display currencies, percentages, and numbers tailored to specific regional formats. • Handle complex pluralization rules and list formatting automatically. • Implement locale-sensitive string comparison and sorting. • Design fallback mechanisms and manage dynamic locale switching in modern applications. You will start with the foundational concepts of locales and language tags before exploring practical, text-based implementation exercises. Through clear explanations and structured code examples, you will learn to apply standard APIs to localize user interfaces. This course is designed for beginner web developers looking to expand their skills; basic familiarity with JavaScript is recommended, but no prior internationalization experience is required.
