Could I make a CONVERSATIONAL JS chat bot this way...?

Question

A chat bot using if() statements and switch() statements.
So I literally output the bot’s response using if() and switch().
Besides things that I can use keywords for like this...
Example:
user: Tell me a good joke;
goodJokes = [“what do you ca..”, “blue is green”, “why did the chic...”];
if UserInput includes(“Tell” “good” + “jokes”){
pickRandom(goodJokes)
}
Using if() I can look for keywords and things like that.
And switch() for absolute answers.

Answer 1

My real questuon is...
What would my code look like...? do u think it would be long as a dictionary ... or meh not that long?
Do you have any tips on this to make it simpler or shorter code?
or, umm should I even try this, or does it sound pointless because it won’t work?
