Difference Between the Spread and Rest Operators in JavaScript

Comments(1)

// We use the spread operator to spread array values or iterables into maybe an array or object.

// While we use the Rest operator to gather the remaining elements passed into a function as an array.

const myFunction = (name1, ...rest) => { // used rest operator here
    console.log(name1);
    console.log(rest);
};

let names = ["John", "Jane", "John", "Joe", "Joel"];
myFunction(...names); // used spread operator here

Spread operator: The spread operator helps us expand an iterable such as an array where multiple arguments are needed
Note: There can be more than one spread operator in javascript functions.

var array1 = [10, 20, 30, 40, 50];
    var array2 = [60, 70, 80, 90, 100];
    var array3 = [...array1, ...array2];
   console.log(array3);


Rest operator: The rest parameter is converse to the spread operator. while spread operator expands elements of an iterable, rest operator compresses them.

 function average(...args) {
        console.log(args);
        var avg =
            args.reduce(function (a, b) {
                return a + b;
           }, 0) / args.length;
        return avg;
    }
    console.log("average of numbers is : "
        + average(1, 2, 3, 4, 5));
    console.log("average of numbers is : "
        + average(1, 2, 3));
