• Question 2: Take input from the user in loop 5 times and find the greatest number. In UI, it should display all the user’s input along with the result.
• Question 3: Build a function that generates and returns the Fibonacci sequence up to a specified number of terms.
• Question 4: Implement a function to remove all duplicate elements from an array.
• Question 5: Prompt the user to get the name, age and occupation. Create the JS object for the inputs and use the for loop to display the key and values of the object.
