JavaScript for Loop — exercises and bug fixes

Use a for loop to append 5 <li> elements to #list, with text "Item 1" through "Item 5".

• Add 5 list items.
• The first item should read "Item 1".
• The fifth item should read "Item 5".

Use a for loop to add up every whole number from 1 to 10, then display the total inside #total as "Total: 55".

Use a for loop to add 5 rows to #table-body, each with two cells: the multiplier (1-5) and its product with 3 (3, 6, 9, 12, 15).

• Add 5 rows to the table body.
• The first row's product should be 3.
• The fifth row's product should be 15.

Use a for loop to add 5 <li> elements to #countdown counting down from 5 to 1 (in that order).

• Add 5 items to the countdown.
• The first item should be 5.
• The last item should be 1.

Use a for loop that steps by 2 to add the even numbers 2, 4, 6, 8, 10 as <li> elements to #evens.

• Add 5 even numbers.
• The first even number should be 2.
• The last even number should be 10.

Add the numbers 1 to 5 and show the total.

Count how many names are in the list and show the number.

Produce "3,2,1" by counting down from three.

Multiply 2, 3 and 4 together and show the product.

From 1 to 6, add just the even values.

This loop is supposed to add 5 list items, but its condition stops it one item short. Fix the loop condition.

• The list should have 5 items.
• The fifth item should read "Item 5".

This loop should sum 1 through 10 (total 55), but it stops before adding 10. Fix the loop condition so the total is correct.

This multiplication-by-4 table should start at 1, but the loop starts at 2, so the first row is missing. Fix the starting value.

• The table should have 5 rows.
• The first row's product should be 4 (1 × 4).

This countdown should reach 1, but the loop condition stops it at 2. Fix the condition so it counts all the way down to 1.

• The countdown should have 5 items.
• The last item should be 1.

This list should show only even numbers (2, 4, 6, 8, 10), but the loop increments by 1 instead of 2, so it lists 1-5 instead. Fix the step.

• The first item should be 2.
• The second item should be 4, not 3.

The loop stops one short, so the total is wrong.

Starting at 1 skips the first item of the array.

Using <= reads one past the end and produces NaN.

The loop counts the wrong way and never runs.

The total is reset inside the loop, so only the last value survives.
