Javascript:Method Chaiining

Implement method chaining.

Code:

function multiply(x) {

    let multiplication = x;

    return {

        multiply(num) {

            multiplication *= num;

            return this;

        },

        getValue() {

            return multiplication;

        }

    };

}

let result = multiply(1).multiply(5).getValue();

console.log(result);

Output:

5
