const searchTerms = new Map();
searchTerms.set(3, 'javascript');
searchTerms.set(1, 'python');
searchTerms.set(12, 'c++');
searchTerms.set(5, 'kotlin');
searchTerms.set(4, 'rust');

Array.from(searchTerms.entries())
  .sort((a, b) => a[0] - b[0])
  .map(([number, term]) => {
    console.log('number-term', number, term);
  });

//     Output:
//
// number-term 1 python
