AWS, JavaScript, React - Deploy Web Apps on the Cloud - JavaScript Do-While Loop

The video tutorial explains the concept of a do while loop in JavaScript. It highlights that a do while loop executes the code block once before checking the condition. An example is provided where a JavaScript function is triggered by a button click, demonstrating the loop's behavior with an initial variable value of 0. The loop increments the variable until it reaches 9. The tutorial also shows what happens when the initial value is set to 11, illustrating that the loop executes once but does not repeat as the condition is not met.

What is the primary characteristic of a do while loop?

• It never executes the code block if the condition is false.

• It executes the code block only if the condition is true.

• It executes the code block once before checking the condition.

• It checks the condition before executing the code block.

In the JavaScript example, what triggers the function containing the do while loop?

• A page load event

• A mouse hover

• A button click

• A form submission

What is the initial value of the variable 'I' in the JavaScript example?

• 10

• 11

• 1

• 0

What happens when the initial value of 'I' is set to 11?

• The loop executes once and stops.

• The loop executes indefinitely.

• The loop does not execute at all.

• The loop executes multiple times.

Why does the loop stop executing when 'I' is initially set to 11?

• Because the variable 'I' is not incremented.

• Because the condition is not met after the first execution.

• Because the condition is met after the first execution.

• Because the loop is set to execute only once.
