What is 'fi-FI' locale code?

Every locale code is a unique identifier for a specific language and country (or region). It is used in software development to localize applications and websites. Locale code is a combination of ISO 639-1 language code and ISO 3166-1 country code. For example, fi_FI is a locale code for Finnish language in Finland. Locale codes are used to define the language and country settings for date, time, currency, and number formatting. They are also used to translate user interfaces and messages in software applications. Locale codes are essential for building multilingual and internationalized software products. They are used in programming languages, frameworks, and libraries to provide internationalization and localization features. Locale codes are also used in databases, operating systems, and web browsers to provide language and country-specific settings. Locale codes are standardized by the International Organization for Standardization (ISO) and are widely used in software development.
