TypedArr (TB09)
1: const str = "Hello, world!";
2: const encoder = new TextEncoder();
3: const encoded = encoder.encode(str); // Encode string as UTF-8
4:
5: const buffer = new ArrayBuffer(encoded.length);
6: const view = new DataView(buffer);
7:
8:
9: for (let i = 0; i < encoded.length; i++) {
10: view.setUint8(i, encoded[i]);
11: }
12:
13: const decoder = new TextDecoder('utf-8'); // Specify encoding
14: const decoded = decoder.decode(buffer);
15:
16: console.log(decoded); // Output: Hello, world!

Working with Strings (UTF-8 Encoding): This example demonstrates how you can encode/decode UTF-8 strings and store them in an ArrayBuffer using DataView. TextEncoder converts the string to UTF-8 byte array, and TextDecoder converts back from UTF-8 array to string. It shows integration of DataView with other API for character encoding. Hello, world!
