Create a heading element for your webpage and nest it within the header element. You may use HTML or JavaScript to complete this requirement. Add content related to Chapters 8, 9 and 10 to the heading 2 element and paragraph elements on the page.
Create a JavaScript file and:
Add a comment with your name and today's date.
Reference your JavaScript file within the index file.
Create and use a JavaScript object.
Use a function to create a new heading element, add content to the new heading element, and display it within an article element on the page.
Create another function that removes a node.
Use a minimum of two different methods from the following list:
getElementsByClassName()
getElementsByName()
getElementsByTagName()
querySelector()
querySelectorAll()
Create other functions as necessary to meet project requirements.
Create and use at least one Event Listener. Do not call any functions from the HTML file.
Comment generously. Include comments to explain the purpose of each variable, function, and statement on your script file.

What are the three uses of a screw?

Create a function (prob3_6) that will do the following: input a positive scalar integer x. if x is odd, multiply it by 3 and add 1. if the given x is even, divide it by 2. repeat this rule on the new value until you get 1, if ever. your program will output how many operations it had to perform to get to 1 and the largest number along the way. for example, start with the number 3: because 3 is odd, we multiply by 3 and add 1 giving us 10. 10 is even so we divide it by 2, giving us 5. 5 is odd so we multiply by 3 and add one, giving us 16. we divide 16 (even) by two giving 8. we divide 8 (even) by two giving 4. we divide 4 (even) by two giving 2. we divide 2 (even) by 2 to give us 1. once we have one, we stop. this example took seven operations to get to one. the largest number we had along the way was 16. every value of n that anyone has ever checked eventually leads to 1, but it is an open mathematical problem (known as the collatz conjectureopens in new tab) whether every value of n eventually leads to 1. your program should include a while loop and an if-statement.
