Prompt() Command

"The prompt command returns a string that is whatever the visitor types into the prompt dialogue box." - Dave McFarland

let randomMaleName = prompt("Choose random male name.") ; let story = "I am a big fan of " + randomMaleName + "." ; document.write(story) ;

When you input Per "Dead" Ohlin as a response to the prompt, there aren't any problems. Why is that? The prompt command returns a string, right?

Not sure I understand your question. What were you expecting to happen?

You are correct, the "prompt" function returns a string. The rest of the example code combines that string with other parts of a sentence and then writes the combined string in the variable "story" to the page.

I'm a bit confused when you say "...there aren't any problems. Why is that?". It sounds like you are expecting some problem, is that so?

Yes because I learned that you cant have quotation marks inside quotation marks (" " " " <-- not good good --> " ' ' " ) without an escape character ().

@ah11 — I see now how that might have been a surprise. The trick is that the issue about quotes only counts when you are constructing a string literal. The quotes you type in to the prompt go straight into the variable so they don't cause any problem when you concatenate them with the other strings.

Happy coding!
