How to use Array.sort() Method and === Operator In Javascript

Using Array.sort() and reverse() Methods

  • Use JavaScript Array.sort() method.
  • In the Comparison condition, Use === operator to compare the Boolean objects.
  • Return 0, 1, and -1 means equal, greater, and smaller respectively depending upon the comparison.

Example: This example implements the above approach. 

Javascript 
let arr = [false, true, false, true, false];

function GFG_Fun() {
    arr.sort(function (x, y) {
        return (x === y) ? 0 : x ? -1 : 1;
    });

    console.log("Sorted Array - [" + arr + "]");
}

GFG_Fun();

Output
Sorted Array - [true,true,false,false,false]
