Chapter VI · Functions
Arguments
Arguments are the actual real values passed into a function when it is invoked.
01 How It Works
Think of handing specific ingredients to a chef at a cooking station.
Arguments map directly onto the function's defined parameters in sequential order.
example.js
function square(num) {
return num * num;
}
square(4); // 4 is the argument
1. Invoke a target function.
2. Pass values or variables inside the parentheses.
3. Receive values via function parameters.
02 Practical Example
Here is how you might see this concept applied in real-world code:
practical.js
function showFullName(first, last) {
console.log(first + " " + last);
}
showFullName("Jane", "Doe");
Key Takeaway
Arguments supply the concrete data required for function execution.
