Sorting an Array in Random Order

Utilizing a sort function as described earlier, you can arrange a numeric array in a random order.

Example

const points = [40, 100, 1, 5, 25, 10];
points.sort(function(){return 0.5 – Math.random()});

Sorting Object Arrays

Objects are commonly found within JavaScript arrays.

Example

const cars = [
  {type:“Volvo”, year:2016},
  {type:“Saab”, year:2001},
  {type:“BMW”, year:2010}
];

Even when objects possess properties of varying data types, the sort() method can still be employed to sort the array.

The solution involves crafting a compare function to compare the property values.

Example

cars.sort(function(a, b){return a.year – b.year});

String property comparisons entail a slightly more intricate process.

Example

cars.sort(function(a, b){
  let x = a.type.toLowerCase();
  let y = b.type.toLowerCase();
  if (x < y) {return –1;}
  if (x > y) {return 1;}
  return 0;
});
