LocalizableString

Used to localize the data, or in simpler terms store the translations for all headings and captions. It is a way to store localized strings in a JSON structure. An object of key–value pairs (or name–value pairs) where key is the identifier for the string, the language code in this case, and the value is the localized string for that language.

Example:

{
    "en": "Dog",
    "fr": "Chien"
}
