Encoding
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
encoder.encodingDOMString- The name of the encoder as a string describing the method the
TextEncoderuses (alwaysutf-8).
- The name of the encoder as a string describing the method the
Methods
encode(input:USVString)Uint8Array- Encodes a string input.
TextDecoder
Background
The TextDecoder interface represents a UTF-8 decoder. Decoders take a stream of bytes as input and emit a stream of code points.
TextDecoder() returns a newly constructed TextDecoder that generates a code-point stream.
Constructor
let decoder = new TextDecoder();
Properties
decoder.encodingDOMString- The name of the decoder that describes the method the
TextDecoderuses.
- The name of the decoder that describes the method the
decoder.fatalboolean- Indicates if the error mode is fatal.
decoder.ignoreBOMboolean- Indicates if the byte-order marker is ignored.
Methods
decode():DOMString- Decodes using the method specified in the
TextDecoderobject. Learn more at MDN’sTextDecoderdocumentation.
