MDN’s new design is in Beta! A sneak peek:

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage 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 specification changes.

The TextDecoder.decode method returns a DOMString containing the text, given in parameters, decoded with the specific method for that TextDecoder object.


b1 = decoder.decode(buffer, options);
b2 = decoder.decode(buffer);
b3 = decoder.decode();


buffer Optional
Is either an ArrayBuffer or an ArrayBufferView containing the text to decode.
options Optional
Is a TextDecodeOptions dictionary with the property:
A Boolean flag indicating that additional data will follow in subsequent calls to decode(). Set to true if processing the data in chunks, and false for the final chunk or if the data is not chunked. It defaults to false.


Specification Status Comment
The definition of 'TextDecoder.decode()' in that specification.
