0 0 2 minutes read

The Javascript array.toLocaleString() is an inbuilt function in JavaScript that is basically used to convert the elements of the given array to a string.
Syntax:

arr.toLocaleString(locales, options)

Return values: It returns a string representing the elements of the array.

JavaScript Version: ECMAScript 1

Examples: In this example, the variable number will be converted into a string using the array.toLocaleString() function.

Input: 
let name = "gfg";
let number = 123;
let 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 the JavaScript program on array.toLocaleString() function:

Example: In this example, we will see the conversion of a number and a date into strings using array.toLocaleString() function.

JavaScript

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

Output:

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