AWS, JavaScript, React - Deploy Web Apps on the Cloud - JavaScript For Loops

The video tutorial explains how to use for loops in programming to execute code repeatedly with different values. It demonstrates setting up a for loop to output numbers from 0 to 10 in an HTML document. The tutorial covers declaring variables, defining loop parameters, and testing the output in a web browser. It also explores modifying the loop's initial and maximum values to change the output range.

What is the primary purpose of using a for loop in programming?

• To execute code once

• To run code multiple times with different values

• To store data

• To debug code

What is the first step in setting up a for loop?

• Test the loop in a browser

• Define the loop parameters

• Output values using document.write

• Declare a variable for initial values

Which function is used to display each value of the loop in the HTML document?

• console.log

• alert

• document.write

• print

What happens if you change the initial value of the count variable to 3?

• The loop starts at 3 and ends at 20

• The loop starts at 3 and ends at 10

• The loop starts at 0 and ends at 3

• The loop does not execute

How can you extend the loop to continue until the value reaches 20?

• Change the loop type

• Change the initial value to 20

• Change the increment value to 20

• Change the maximum value to 20
