How to sorting an array without using loops in Node.js ?

Last Updated : 31 Aug, 2020

The setInterval() method repeats or re-schedules the given function at every given time-interval. It is somewhat like window.setInterval() Method of JavaScript API, however, a string of code can't be passed to get it executed.

Syntax:

setInterval(timerFunction, millisecondsTime);

Parameter: It accepts two parameters which are mentioned above and described below:

timerFunction <function>: It is the function to be executed.
millisecondsTime <Time>: It indicates a period of time between each execution.

The setTimeout() method is used to schedule code execution after waiting for a specified number of milliseconds. It is somewhat like window.setTimeout() Method of JavaScript API, however a string of code can't be passed to get it executed.

Syntax:

setTimeout(timerFunction, millisecondsTime);

Parameter: It accepts two parameters which are mentioned above and described below:

timerFunction <function>: It is the function to be executed.
millisecondsTime <Time>: It indicates a period of time between each execution.

Examples:

Input: Array = [ 46, 55, 2, 100, 0, 500 ]
Output: [0, 2, 46, 55, 100, 500]

Input: Array = [8, 9, 2, 7, 18, 5, 25]
Output: [ 2, 5, 7, 8, 9, 18, 25 ]

Approach: The sorting requires visiting each element and then performing some operations, which requires for loop to visit those elements.

Now here, we can use setInterval() method to visit all those elements, and perform those operations.

The below code illustrates the above approach in JavaScript Language.

File Name: Index.js

javascript

const arr = [46, 55, 2, 100, 0, 500];
const l = arr.length;
var arr1 = [];
var j = 0;

var myVar1 = setInterval(myTimer1, 1);

function myTimer1() {
   const min = Math.min.apply(null, arr);
   arr1.push(min);

   // arr[arr.indexOf(min)]=Math.max.apply(null, arr);
   arr.splice(arr.indexOf(min), 1);
   j++;
   
   if(j == l){
     clearInterval(myVar1);    
     console.log(arr1);
   }
}
