JavaScript implements an array of objects sorted by different fields

Suppose there is an array of objects that we want to sort by an array of object properties, and the comparison function passed to the arrays sort () method receives two parameters, that is, the value to compare. However, we need a way to indicate which property to sort by. To solve this problem, you can define a function that receives a property name and then creates a comparison function based on the property name, which is the definition of the function.
function Createcomparionfun (PropertyName) {    return function (object1,object2)   {       var value1=object1[ PropertyName];       var value2=object2[propertyname];      if (value1<value2)      {         return-1;      } else if (value1>value2)      {          return 1;      } else {        return 0;}}   }


The above function can be used in this case as in the following example.

var data=[{name: "Zom", Age:18},{name: "NBD", age:20}];d Ata.sort (creatcomparionfun ("name")); alert (data[0].name);// Nbddata.sort (Creatcomparionfun ("Age")); alert (data[0].name);//zom
This makes it possible to sort by different attributes.
