const encoder = new TextEncoder(); const data = encoder.encode("Hello world\n"); await Deno.writeFile("hello1.txt", data); // overwrite "hello1.txt" or create it await Deno.writeFile("hello2.txt", data, {create: false}); // only works if "hello2.txt" exists await Deno.writeFile("hello3.txt", data, {mode: 0o777}); // set permissions on new file await Deno.writeFile("hello4.txt", data, {append: true}); // add data to the end of the file
