    This is an experimental technology
    Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.

    The TextDecoder interface represents a decoder for a specific method, that is a specific character encoding, like utf-8, iso-8859-2, koi8, cp1261, gbk, ... A decoder takes a stream of bytes as input and emits a stream of code points. For a more scalable, non-native library, see StringView – a C-like representation of strings based on typed arrays.


    The TextDecoder interface doesn't inherit any property.

    TextDecoder.encoding Read only
    Is a DOMString containing the name of the decoder, that is a string describing the method the TextDecoder will use.
