encodeInto
fun encodeInto(source: String, destination: Uint8Array<ArrayBufferLike>): TextEncoderEncodeIntoResult(source)
The TextEncoder.encodeInto() method takes a string to encode and a destination Uint8Array to put resulting UTF-8 encoded text into, and returns an object indicating the progress of the encoding. This is potentially more performant than the encode() method — especially when the target buffer is a view into a Wasm heap.
