Sort array of objects

Question

I have an array of object literals like this:

var myArr = [];

myArr[0] = {
   \'score\': 4,
   \'name\': \'foo\'
}

myArr[1] = {
   \'score\': 1,
   \'name\         


        

Answer 1

You could have a look at the Array.sort documentation on MDN. Specifically at the documentation about providing a custom compareFunction

Answer 2

const myArray = [  
    {
   'score': 4,
   'name': 'foo'
},{
   'score': 1,
   'name': 'bar'
},{
   'score': 3,
   'name': 'foobar'
}
]

const myOrderedArray = _.sortBy(myArray, o => o.name);
console.log(myOrderedArray);

lodash sortBy

Answer 3

Try myArr.sort(function (a, b) {return a.score - b.score});

The way the array elements are sorted depends on what number the function passed in returns:

• < 0 (negative number): a goes ahead of b
• > 0 (positive number): b goes ahead of a
• 0: In this cases the two numbers will be adjacent in the sorted list. However, the sort is not guaranteed to be stable: the order of a and b relative to each other may change.
