const encoder = new TextEncoder() const view = encoder.encode('€') console.log(view); // Uint8Array(3) [226, 130, 172]
TextEncoder()
Returns a newly constructed TextEncoder
that will generate a byte stream with UTF-8 encoding.
The TextEncoder
interface doesn't inherit any property.
TextEncoder.prototype.encoding
Read only
Always returns "utf-8
".
The TextEncoder
interface doesn't inherit any method.
TextEncoder.encode()
Takes a USVString
as input, and returns a Uint8Array
containing UTF-8 encoded text.
TextEncoder.encodeInto()
Takes a USVString
to encode and a destination Uint8Array
to put resulting UTF-8 encoded text into, and returns a dictionary object indicating the progress of the encoding. This is potentially more performant than the older encode()
method.
