Callback: A function passed as an argument to other function is called callback function.
function calculation(a, b, fn) { return fn(a, b); } function add(a, b) { return a + b; } function mul(a, b) { return a * b; } function sub(a, b) { return a - b; } function div(a, b) { return a / b; } console.log(calculation(4, 2, mul)); while passing function as argument to another function make sure to ignore appending parenthesis.
Thanks.

Purposefully, wrote functions instead of arrow functions. It will be more intuitive while reading.
Thank you for suggestion. Its colorful code now.
