TextEncoder

Background

The TextEncoder takes a stream of code points as input and emits a stream of bytes. Encoding types passed to the constructor are ignored and a UTF-8 TextEncoder is created.

TextEncoder() returns a newly constructed TextEncoder that generates a byte stream with UTF-8 encoding. TextEncoder takes no parameters and throws no exceptions.

Constructor

let encoder = new TextEncoder()

Properties

  • encoding DOMString read-only
    • The name of the encoder as a string describing the method the TextEncoder uses (always utf-8).

Properties

  • encoding DOMString read-only

    • The name of the decoder that describes the method the TextDecoder uses.
  • fatal boolean read-only

    • Indicates if the error mode is fatal.
