Tell javascript if Else Unexpected Token else

Question

I teach myself JavaScript using Code Academy, and I'm trying to make simple code so that when I request a response, a response is given, the user's response gives an answer.

Example.

prompt says "what your favourite colour?" user says "blue" response "that the same colour as the sky!" 

But when I try to add different parameters, I get a syntax error: unexpected else token.

I tried to make sure that if I asked a question, the answer would get an answer, but something else would get the answer.

Here is the code.

 prompt("what do you want?"); if ("coke"); {console.log ("no coke, pepsi.")}; else console.log ("pepsi only.")}; 

If anyone has any ideas, I would be very grateful!

You need to save the return value of the prompt if you want to use it later. In addition, you have some syntax errors that should be fixed:

 var answer = prompt('what do you want?'); if (answer === 'coke') { console.log('you said coke!'); } else { console.log('why didn\'t you say coke!?'); } 

You can also use the switch as you get more cases:

 var answer = prompt('what do you want?'); switch (answer) { case 'coke': console.log('you said coke!'); break; default: console.log('why didn\'t you say coke!?'); break; } 

Or an object, as most people prefer this:

 var answer = prompt('what do you want?'); var responses = { coke: 'you said coke!', defaultResponse: 'why didn\'t you say coke!?' }; console.log(responses[answer] || responses.defaultResponse); 

Answer 2

If the end does not require a semicolon. Instead, run:

 if ("coke") { console.log ("no coke, pepsi."); } else { console.log ("pepsi only."); } 

Answer 3

Remove the end semicolons:

 prompt("what do you want?"); if ("coke") { console.log ("no coke, pepsi."); } else { console.log ("pepsi only."); } 

Answer 4

 var name = prompt("what do you want?"); if (name == "coke") { console.log ("no coke, pepsi.") } else { console.log ("pepsi only.") } 

As above

Answer 5

You have a semicolon after closing. Try:

 var ans = prompt("what do you want?"); if (ans == "coke") { console.log ("no coke, pepsi."); } else { console.log ("pepsi only."); } 

Answer 6

DO NOT REALLY DO

  if (ans == "whatever") { console.log ("whatever"); } else { console.log ("whatever."); } 

DO

  if (ans == "whatever") { confirm ("whatever"); } else { confirm ("whatever."); } 

Answer 7

A variable needs to be identified. Also, bracketing and half-columns between "if" "else" are problematic. I'm not sure about console log , but if you want a warning popup to try this:

 var brand = prompt ('what do you want?'); if (brand="coke") { alert ("no coke, pepsi.") }else { alert ("pepsi only.") };
