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.
