Why yet another javascript date and time library

  • Popular javascript date libraries like moment or date-utils are wrappers around the native javascript Date object, providing syntactic sugar. The native Date object always consist of a date, time and a timezone part. In opposite to that, js-joda is a standalone date and time implementation.
  • The API has a domain-driven design with classes for the different use cases, like LocalDate, ZonedDateTime or Period. For examples LocalDate allows to handle dates like birthdays or holidays in a clean and error-safe way, especially if these dates are persisted to an external server.
  • js-joda is immutable. Immutability aligns well with pure functions and with the architecture of frameworks like React and Flux.
