TextEncoder takes a stream of code points as input and emits a stream of bytes. For a more scalable, non-native library, see
StringView – a C-like representation of strings based on typed arrays.
Note: Firefox, Chrome and Opera used to have support for encoding types other than
utf-8 (such as
gbk). As of Firefox 48 (ticket), Chrome 54 (ticket) and Opera 41, no other encoding types are available other than
utf-8, in order to match the spec. In all cases, passing in an encoding type to the constructor will be ignored and a utf-8 TextEncoder will be created (the TextDecoder still allows for other decoding types).
Note: There is a polyfill implementation to support all the legacy encodings in GitHub.
- Returns a newly constructed
TextEncoderthat will generate a byte stream with utf-8 encoding.
TextEncoder interface doesn't inherit any property.
- Is a
DOMStringcontaining the name of the encoder, that is a string describing the method the
TextEncoder interface doesn't inherit any method.

 An earlier, and slightly different, version of the specification was implemented in Firefox 18.
 As of Firefox 48, Chrome 54 and Opera 41, no other encoding types are allowed other than utf-8.
