Finding Object With Lowest Value For Some Key, In Javascript

In my Javascript program, I have a list of Person objects. For example [ 'Michael': { 'age': 45, 'position': 'manager', ... }, 'Dwight':

Solution 1:

You can sort the persons array by age property and pick first one:

var persons = [
    { name: 'Michael', age: 45, position: 'manager' },
    { name: 'Dwight', age: 36, position: 'assistant manager' },
    { name: 'Foo', age: 99, position: 'foo' },
    { name: 'Bar', age: 37, position: 'bar' }
];

persons.sort(function(a, b) {
    return a.age > b.age;
});

console.log('Youngest person: ', persons[0]);
