// Example writing to stdout
let contentBytes = new TextEncoder().encode("Hello World");
writeAllSync(Deno.stdout, contentBytes);

// Example writing to file
contentBytes = new TextEncoder().encode("Hello World");
const file = Deno.openSync('test.file', {write: true});
writeAllSync(file, contentBytes);
file.close();

// Example writing to buffer
contentBytes = new TextEncoder().encode("Hello World");
