// You will be given an array of objects (associative arrays in PHP) representing data about developers who have
// signed up to attend the next coding meetup that you are organizing. The list is ordered according to who
// signed up first.

// Your task is to return one of the following strings:
// < firstName here >, < country here > of the first Python developer who has signed up; or
// There will be no Python developers if no Python developer has signed up.
// For example, given the following input array:

// var list1 = [
//   { firstName: 'Mark', lastName: 'G.', country: 'Scotland', continent: 'Europe', age: 22, language: 'JavaScript' },
//   { firstName: 'Victoria', lastName: 'T.', country: 'Puerto Rico', continent: 'Americas', age: 30, language: 'Python' },
//   { firstName: 'Emma', lastName: 'B.', country: 'Norway', continent: 'Europe', age: 19, language: 'Clojure' }
// ];

// your function should return Victoria, Puerto Rico.

// solution 1:

function getFirstPython(list) {
  for (const elem in list) {
    if (list[elem].language == 'Python') return `${list[elem].firstName}, ${list[elem].country}`;
  }
  return 'There will be no Python developers';
}

// solution 2:
const getFirstPython = list => {
  const pythonDev = list.find(({ language }) => language === 'Python');
  return pythonDev ? `${pythonDev.firstName}, ${pythonDev.country}` : 'There will be no Python developers';
};
