can you specify a source language for the google translate API?

[talkingtab]

I would like to be able to specify a source language. I know I can autodetect, but is there a way to specify exactly the language "i" is and in Czech and so if I want to translate to French, how would I do that?

// Imports the Google Cloud client library
const Translate = require('@google-cloud/translate');

// Instantiates a client
const translate = Translate();

// The text to translate
const text = 'Ahoj světe!';

// The source language
const source = 'cs';

// The target language
const target = 'fr';

const options = {
  from: source,
  to: target
};

translate.translate(text, options)
  .then((results) => {
    console.log(JSON.stringify(results, null, 2));
  })
  .catch((err) => {
    console.error('ERROR:', err);
  });
