In this tutorials will teach how to make a calculator in Node Js using Arrow Function step by step.

const main =(operator,num1,num2) =>
{
    if(operator == "+")
    {
        const data = add(num1,num2);
        console.log(data)
    }
    else if(operator == "-")
    {
        const data = subtract(num1,num2);
        console.log(data)
    }
    else if(operator == "*")
    {
        const data = multiply(num1,num2);
        console.log(data)
    }
    else if(operator == "/")
    {
        const data = divi(num1, num2);
        console.log(data)
    }
    else
    {
        console.log("There is Problem")
    }

};


const add = (num1,num2) =>
{
    return num1 + num2;
}

const subtract = (num1,num2) =>
{
    return num1 - num2;
}

const multiply = (num1,num2) =>
{
    return num1 * num2;
}

const divi = (num1,num2) =>
{
    return num1 / num2;
}

main("+", 2,6);
main("-", 8,6);
main("*", 2,4);
main("/", 6,2);

i have attached the video link below. which will do this tutorials step by step.
