JavaScript Mastery from Zero to Hero - Prepare for Coding Interviews - Interview Solution II - Sort and Order Numbers in

The video tutorial covers modifying a function to sort and order elements, introducing a solution using concatenation to optimize performance. The concat method is explained, highlighting its efficiency in joining arrays without altering the original. The tutorial concludes with a successful implementation of the solution and encouragement to continue learning.

What is the initial task described in the video?

• To write a function to calculate averages

• To create a new function from scratch

• To modify a function to sort and order elements

• To delete an existing function

What is the main advantage of using concatenation as described in the video?

• It saves time and computational energy

• It increases the complexity of the code

• It requires more computational energy

• It makes the code harder to read

What does the concat method do?

• It deletes elements from an array

• It sorts an array in descending order

• It joins two arrays and returns a new array

• It changes the existing array

How does the concat method affect the original array?

• It leaves the original array unchanged

• It modifies the original array

• It duplicates the original array

• It deletes the original array

What is the final step after using the concat method in the video?

• To sort the numbers using a comma-separated format

• To run a loop to check conditions

• To refresh the page to see the results

• To delete the concatenated array
