Modern Web Design with HTML5, CSS3, and JavaScript - Using Continue and Break-in for loop and While Loop

The video tutorial explains the use of break and continue statements in JavaScript. It starts with an introduction to the break statement, showing how it terminates loops or switches. An example with a while loop is provided, demonstrating how the loop stops when a condition is met. The tutorial then covers the continue statement, explaining its role in skipping iterations. An example with a while loop shows how using continue can lead to an infinite loop. The tutorial concludes with examples of using break and continue in a for loop, highlighting their effects on loop execution.

What is the primary function of the break statement in JavaScript?

• To skip the current iteration of a loop

• To restart a loop from the beginning

• To terminate a loop or switch statement

• To pause the execution of a loop temporarily

In the given example, what happens when the value of X reaches 5 in the while loop?

• The loop continues without any change

• The loop pauses and resumes after a delay

• The loop skips the current iteration

• The loop terminates immediately

What issue can arise when using the continue statement in a while loop?

• It can cause a syntax error

• It can skip multiple iterations unintentionally

• It can create an infinite loop

• It can cause the loop to terminate prematurely

How does the continue statement behave differently in a for loop compared to a while loop?

• It causes the loop to terminate

• It skips the current iteration without causing an infinite loop

• It restarts the loop from the beginning

• It pauses the loop execution

What is the effect of the break statement when used in a for loop?

• It restarts the loop from the beginning

• It terminates the loop immediately

• It pauses the loop execution

• It skips the current iteration

In the for loop example, what happens when the value of I is 3?

• The loop terminates

• The loop pauses

• The loop restarts

• The loop skips the iteration

What is the output in the console when the break statement is executed at I = 8 in the for loop?

• The loop outputs numbers up to 9 and stops

• The loop outputs numbers up to 8 and stops

• The loop outputs numbers up to 7 and stops

• The loop continues without interruption
