JavaScript | array.toLocaleString() function

The array.toLocaleString() is an inbuilt function in JavaScript which is basically used to convert the element of the given array to string.
Syntax:

arr.toLocaleString();

Return values:
It return a string representing the elements of the array.
JavaScript Version:
ECMAScript 1
Examples:

Input: 
var name = "gfg";
var number = 123;
var A = [ name, number ];
Output:
> "gfg, 123"

Here as we see that in input there are two variables containing elements but in output these are converted into a string.
Let’s see JavaScript program on array.toLocaleString() function:

// taking inputs. 
var name = "geeksforgeeks"; 
var number = 567; 
  
// It will give current date and time. 
var date = new Date(); 
  
// Here A is an array containing elements of above variables. 
var A = [ name, number, date ]; 
  
// applying array.toLocaleString function. 
var string = A.toLocaleString(); 
  
// printing string. 
console.log(string); 

Output:

> "geeksforgeeks, 567, 2/18/2018, 10:41:20 AM"

Application:
The array.toLocaleString() function in JavaScript is used whenever we need to convert the element of the given array to a string.
Let’s see JavaScript program on array.toLocaleString() function:

// taking inputs. 
var name = [ "Ram", "Sheeta", "Geeta" ]; 
var number1 = 3.45; 
var number2 = [ 23, 34, 54 ]; 
  
// Here A is an array containing elements of above variables. 
var A = [ name, number1, number2 ]; 
  
// appling array.toLocaleString function. 
var string = A.toLocaleString(); 
  
// printing string. 
console.log(string);
