Idea: file/file.ts -- ergonomics for interacting with files

[lucascaro]

Extending the core with more ergonomic file functions:

example:

export function fileExists(filename: string): boolean {
  return readDirSync(".").filter((f) => f.name === filename).length > 0;
}

export function writeStringSync(filename: string, data: string) {
  const encoder = new TextEncoder();
  writeFileSync(filename, encoder.encode(data));
}

export function readStringSync(filename: string, encoding: string) {
  const decoder = new TextDecoder(encoding);
  return decoder.decode(readFileSync(filename));
}

etc.

If this seems useful and in line with deno_std then I can propose a more complete API.

String functions seem good!
