Learn TypeScript course tsc not compiling

I am about halfway through the Learn TypeScript course, and it appears that the tsc compiler is not working and will not allow me to proceed to the next chapter of the course. In earlier lessons, it seemed to be having issues, but I was able to navigate forward anyway. In the Array section about Spread Syntax, it will not compile and also will not allow me to proceed even though the code I’ve entered is correct. This has been a great course so far, and I don’t wish to stop here.

Edit: I replaced my code with the code solution and it let me through.
