JavaScript arrays often contain objects:
Example
const cars = [
{type:"Volvo", year:2016},
{type:"Saab", year:2001},
{type:"BMW", year:2010}
];
{type:"Volvo", year:2016},
{type:"Saab", year:2001},
{type:"BMW", year:2010}
];
Even if objects have properties of different data types, the sort() method can be used to sort the array.
The solution is to write a compare function to compare the property values:
Example
cars.sort(function(a, b){return a.year - b.year});
Comparing string properties is a little more complex:
Example
cars.sort(function(a, b){
var x = a.type.toLowerCase();
var y = b.type.toLowerCase();
if (x < y) {return -1;}
if (x > y) {return 1;}
return 0;
});
var x = a.type.toLowerCase();
var y = b.type.toLowerCase();
if (x < y) {return -1;}
if (x > y) {return 1;}
return 0;
});
