Sorting array of arrays of objects by value

Question

There is an array of arrays: var people = [[{name: "John", age: "15"}], [{name: "Maria", age: "26"}], [{name: "Alex", age: "9"}]] How can I move "John" to the end of people by his age value? I'm honestly beginner in JS and looking for any help with this task

Answer 1

var people = [[{name: "John", age: 15}], [{name: "Maria", age: 26}], [{name: "Alex", age: 9}]];

people.sort((a,b) => a[0].age - b[0].age);

console.log(people);

Observations:

• John would not be at the end if sorted by age -- his age is in the middle
• You should use integers for your ages. If you don't wrap your sort function values in parseInt.
• The array-of-one-element-arrays thing doesn't seem to make sense -- you may want to rethink that structure.
