  This is:
  
  const fs = require('fs');
  const { resolve } = require('path');
  
  // File name
  const file_name_input = '1.in.json';
  const file_name_output = '1.out.json';
  
  // Read file
  const data = fs.readFileSync(resolve(__dirname, file_name_input), 'utf8');
  console.log(data);
  
  // Parse JSON
  var json = JSON.parse(data);
  
  // Count names
  var names = {};
  json.forEach(function(item) {
  if (names[item.name] === undefined) {
  names[item.name] = [item.id];
  } else {
  names[item.name].push(item.id);
  }
  });
  console.log(names);
  
  // Generate output
  var output = [];
  for (var el in names) {
  output.push({
  name: el,
  count: names[el].length,
  ids: names[el]
  });
  }
  console.log(output);
  
  // Write to file
  fs.writeFileSync(resolve(__dirname, file_name_output), JSON.stringify(output));
