javascript - How do I call a function inside of another function?

Question

I just want to know how to call a javascript function inside another function. If I have the code below, how do I call the second function inside the first?

function function_one()
{
alert("The function called 'function_one' has been called.")
//Here I would like to call function_two.
}

function function_two()
{
alert("The function called 'function_two' has been called.")
}

Answer 1

function function_one() {
    function_two(); // considering the next alert, I figured you wanted to call function_two first
    alert("The function called 'function_one' has been called.");
}

function function_two() {
    alert("The function called 'function_two' has been called.");
}

function_one();
