The video tutorial introduces a third solution for repeating strings using JavaScript. It explains how to use the array keyword and the fill method to achieve this. The tutorial demonstrates how to dynamically adjust the number of repetitions using a variable, providing a practical example of the solution in action.

What is the main focus of Solution 3 introduced in the video?

• Debugging a code

• Creating a new array

• Solving a math problem

• Using a new method to repeat strings

Which JavaScript keyword is highlighted for solving the problem in the second section?

• Function

• String

• Object

• Array

What method is used to fill the array with a specific value?

• Map

• Fill

• Pop

• Push

How does changing the number in the array parentheses affect the output?

• It has no effect

• It changes the data type

• It alters the string content

• It modifies the number of repetitions

What is the final outcome when the number in the array is dynamically switched with NUM?

• The array becomes empty

• The string is reversed

• The string is repeated dynamically

• The array is deleted
