Why do we write functions?
I. Make our code easier to understand by giving a readable name to a group of instructions II. Avoid writing repeated code III. Make our code reusable

When we put a variable between parenthesis, what is it called?

In the following function printThreeTimes:

function printThreeTimes(word){
println(word);
println(word);
println(word);
}

What is the parameter of the function?

On which line is the "call" to the function doubleNumber on the video? (video: 4:50 )

What would I get if I called doubleNumber(10); ? (video: 5:01 )

True or False: Functions must have parameters.

How many parameters does the function sum use?

What would get printed if we added the code,
sum(4, 3); ?

What happens if you try to print a function call when the function doesn't have a return value?

console.log( printNumbers(13,15,17) );
console.log ( sum(13,15,17) );

Code along with the video3 and revise the function doubleNumber to return a value.( video:2:15)

What happens if you try to call the function with a return value like below?
doubleNumber(6);
randomNumber(1,10);

Revise doubleNumber(x) function and call it inside doubleNumberBtn as shown below.

What is printed on the display?

Revise your doubleNumber() function to return value instead of printing it. Replace all code inside doubleNumberBtn to below segment.var numApples=4;var twiceAsMany=doubleNumber(numApples);println("Before : "+numApples);println("After : "+twiceAsMany);Will will be printed when this code is run?
