Accept an Indefinite Number of Arguments in JavaScript

To accept an indefinite number of arguments in JavaScript, we use the Rest Parameter.

In JavaScript, the rest parameter syntax allows you to represent an indefinite number of arguments as an array within a function parameter. It provides a convenient way to work with functions that can accept a variable number of arguments.

The rest parameter is indicated by three dots (…) followed by a parameter name. Let’s write a JavaScript function that can take an indefinite number of parameters:


   function add(...elements){
     let sum = 0;
     for(let element of elements){
       sum+= element;
     }
     return sum;
   }
   console.log(add(2,4,6)); //12
