Javanese script is one of Indonesia's traditional scripts developed on the island of Java. The script is primarily used to write the Javanese language and has also been used to write several other regional languages such as Sundanese and Madurese, the regional lingua franca Malay, as well as the historical languages Kawi and Sanskrit. It heavily influenced the Balinese script from which the writing system for Sasak developed. Javanese script was actively used by the Javanese people for writing day-to-day and literary texts from at least the mid-16th century CE until the mid-20th century CE, before it was gradually supplanted by the Latin alphabet. Today, the script is taught in the Yogyakarta Special Region as well as the provinces of Central Java and East Java as part of the local curriculum, but with very limited function in everyday use.
