Internationalization is crucial for modern companies as it allows them to cater to a global audience by supporting multiple languages and regions. Effective internationalization involves abstracting culture- and locale-specific elements from the software, while localization is the process of creating these specific elements for every different locale. A managed service can help handle the translation process, communication pathways, user profiles, and data logging, allowing developers to focus on providing translations at their own pace. There are various tools available for implementing internationalization, including open-source libraries and frameworks such as i18next, FormatJS, GlobalizeJS, Ruby on Rails, and Polyglot.js. When building an i18n notification workflow, it's essential to consider the time and resources required, weighing the benefits of expediency and user engagement against the potential complexity and cost of implementing internationalization logic from scratch.
