Passing Data into Functions
We can pass data into functions using parameters:
function funcName(parameter1, parameter2, ...) {
// your code here…
}
A parameter acts like a local variable inside the function. However, it takes up the value of the corresponding argument that is passed into the function at the function call.
12345678function sum(a, b) { console.log(a + b); } sum(1, 2); // Output: 3 sum(5, 10); // Output: 15 sum(20, 30); // Output: 50 sum(33, 37); // Output: 70
- An argument is the actual value passed into a function when calling it:
- Example: In
sum(1, 2), the values1and2are arguments;
- Example: In
- A parameter is a placeholder inside the function definition that receives the argument’s value:
- Example: In
function sum(a, b),aandbare parameters.
- Example: In
A function in which other functions are called is known as a compound function. A compound function combines smaller functions to accomplish a larger task.
1. How many parameters does this function have?
2. What will be the output of this code?
3. Which of the following is true?
