accept unlimited parameters in javascript

In this tutorial, we will see how to accept unlimited arguments in a JavaScript function.

A function is block of code that can hold and process a logic. Functions in JavaScript can be declared using the function keyword or arrow function.

function sum(){
console.log("this is a function.");

Function With Parameters

Functions can also have parameters and the number of parameters supplied must be equal to the number of parameters passed.

function sum(a,b){
return a + b;
console.log(sum(5,5)); //10

Function With Unlimited Arguments

Functions can also take unlimited number of parameters as well. To accept an unlimited number of arguments in a JavaScript function, we will use the spread operator.

 function sum(...nums){
   let sum = nums.reduce((a, b) => {
     return a + b;
   return sum

The above function will accept unlimited number of parameters in the JavaScript function. The function returns a sum of all the passed arguments.
