You can remove spaces using replace.

If you wanted to remove only spaces, you could use ".replace(/ /g, "")". Or if you want to remove any whitespace you could use ".replace(/\s/g, "")". For example, if you wanted to convert case and remove whitespace at the same time:

fruit = "B an   a N a";
newfruit = fruit.toLowerCase().replace(/\s/g, "");
// newfruit now contains "banana"

Thanks I added this in my program and it works

var answer = prompt('What programming language is the name of a gem?'); if ( answer.toUpperCase() .replace(/\s/g, "") === 'RUBY' ) { document.write("<p>That's right!</p>"); } else { document.write("<p>Sorry, that's wrong.</p>"); }

I would point out that this is not a common concern, and in some cases an answer may require more than one word so the space would be significant.
