Hi @Xcrimson

// running tests
You should use the concatenation operator on your result variable.
You should concatenate row to your result variable.
You should assign the result of your concatenation back to the result variable.
// tests completed
// console output
Uncaught TypeError: “row” is read-only

The console is giving you some clues.

  1. Uncaught TypeError: “row” is read-only

You declared row with a const declaration, therefore it cannot change.
const meaning constant.

  1. You should assign the result of your concatenation back to the result

Your code is assigning it to row

  1. You should concatenate row to your result variable.
    Here the instructions are asking for a specific order of variables.

Reread the example to so you can understand the syntax required.

You can do a similar thing with a string value, by appending a new string to an existing string. For example, hello = hello + " World"; would add the string " World" to the existing string stored in the hello variable. This is called concatenation.

Happy coding

heyy @Xcrimson the after trying to figure this one out for the past our the answer should be:
---- solution removed

Enjoy!

It is great that you solved the challenge, but instead of posting your full working solution, it is best to stay focused on answering the original poster’s question(s) and help guide them with hints and suggestions to solve their own issues with the challenge.

We are trying to cut back on the number of spoiler solutions found on the forum and instead focus on helping other campers with their questions and definitely not posting full working solutions.

Alright then. Will do next time.
