How to get the min and max value of a property in an array of objects with TypeScript

Answer 1

const objArr = [
  { id: 34, language: 'javascript' },
  { id: 28, language: 'node.js' },
  { id: 18, language: 'typescript' },
  { id: 70, language: 'php' },
  { id: 41, language: 'java' }
];

const ids = objArr.map(object => {
  	return object.id;
});

const max_id_value = Math.max(...ids);
console.log(max_id_value); 

const min_id_value = Math.min(...ids);
console.log(min_id_value);
