Modern Web Design with HTML5, CSS3, and JavaScript - JavaScript Function Return

The video tutorial introduces functions, explaining their purpose and benefits in creating cleaner code. It demonstrates creating a function called 'adder' that multiplies two numbers and returns the result. The tutorial discusses using return values and assigning them to variables. A challenge is presented to create functions for basic arithmetic operations, followed by a solution walkthrough. The video emphasizes understanding function parameters, return values, and console output.

What is the primary benefit of using functions in code?

• They make the code run faster.

• They allow for cleaner and more organized code.

• They automatically debug the code.

• They eliminate the need for variables.

What does the 'adder' function do with the two arguments it receives?

• It divides the first by the second.

• It adds them together.

• It subtracts the second from the first.

• It logs them to the console and multiplies them.

How can you store the result of a function call in a variable?

• By using the 'console.log' method.

• By using the 'return' keyword.

• By declaring the variable inside the function.

• By assigning the function call to a variable.

What happens if you call a function without storing its result in a variable?

• The result is lost.

• The function does not execute.

• The result is immediately output to the console.

• The result is automatically stored in a global variable.
