TextEncoder

The TextEncoder interface takes a stream of code points as input and emits a stream of UTF-8 bytes.

Note: This feature is available in Web Workers

Example

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.

The TextEncoder interface doesn't inherit any method.

TextEncoder.prototype.encode(): Takes a USVString as input, and returns a Uint8Array containing UTF-8 encoded text.
TextEncoder.prototype.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.
