const [error, result] = tryCatch(fn, '{"test": "ok"}');

// or

const fn = () => JSON.parse('{"test": "ok"}');
const [error, result] = tryCatch(fn);

const fn = () => JSON.parse(param);
const [error, result] = tryCatch(fn);

Asynchronous examples (Async / Await)

(async () => {
  
  const axios = require('axios');
  
  const fn = async () => await axios.get('https://myapi.com/posts'); // Returns a promise
  const [error, result] = await tryCatchAsync(fn); // Execute and resolve a promise

  // or

  const fn = () => axios.get('https://myapi.com/users'); // Returns a promise
  const [error, result] = await tryCatchAsync(fn); // Execute and resolve a promise

  console.log(result.data);
  
})();
