I don't understand why did we use a while loop here: What will happen if we don't use it? If I just removed the while(true) and the break, the program will convert text just when the user typed the text and hit the enter button, ain't I right?
while(true)
{
Console.Write(": ");
string input = Console.ReadLine();
if(string.IsNullOrWhiteSpace(input))
{
break;
}
string output = MorseCodeTranslator.ToMorse(input);
Console.WriteLine(output);
}

Without the loop the code will still work fine but it will only translate one sentence then end the program, which is not how Jeremy wanted the program to act.
Using an infinite while loop that only ends when it encounters a break statement is a pretty common way of creating user prompts when you don't know how many times a user will want to enter info. It's something you'll see more of and probably use yourself when you get farther into programming more complex applications.
