What's Internationalization Libraries for Web Development?

Internationalization (i18n) libraries help developers create applications that can support multiple languages and regions. They provide tools for translating text, formatting dates and numbers, and managing locale-specific content. These libraries are essential for building applications that cater to a global audience, ensuring that users can interact with the software in their preferred language. Each library has its own strengths and use cases, making it important to choose the right one based on the project requirements and technology stack.
