0:00.0	You're listening to Syntax, the podcast with the tastiest web development treats out there.
0:06.0	Strap yourself in and get ready. Here is Scott Zelensky and West Boss.
0:10.9	Welcome to Syntax. We've got us stumped for you today. This is the show where Scott and I
0:16.8	ask each other interview questions on coding. So JavaScript, CSS, Node, TypeScript, you name it.
0:24.0	In the past, we've done this where we find a list of interview questions and we ask each
0:28.5	other and we've sort of used them all. That's why we haven't done a stump in a while. However,
0:34.7	our Gordon Xavier AI chat GPT is here with unlimited questions to ask us, which is really
0:43.2	cool. So we're going to ask chat GPT to give us questions based on difficulty and we'll see if
0:52.0	the robots are going to beat us or not. Yeah. And to do this, I think we're we're going to be trying

1:36.0	interview questions. I'd like you to give a unique question for us to answer along with an answer.
1:46.8	So are you are you looking at the prompt I wrote? No, I was just coming up with that in my head.
1:51.3	Okay. So yeah, that's pretty much exactly not exactly, but pretty close to what I had asked it.
1:56.9	So I this morning I was going back and forth and looking at the questions and initially the
2:01.9	question were very good and then the questions were too easy. So I wrote this prompt and I think
2:08.2	it works pretty well. I said you are a game show host that ask web development interview style
