Can anyone help men with this bit if if/else syntax?

It says that my first line is wrong when I add the else block

app.js 
var answer = prompt ('What is the best programming language?');

if (answer === 'JavaScript') {
  alert("You are correct");

else  {
   alert("JavaScript is the best language!");
}

Its a syntax error so you should be looking for proper quotes, methods being written correctly etc. and in your case all brackets must opened and closed.

var answer = prompt ("What is the best programming language?");

if (answer === "JavaScript") {
  alert("You are correct");
}
else  {
   alert("JavaScript is the best language!");
}

You have unmatched braces. It looks like you accidentally erased the closing brace after the first alert.

Just restore that character and you'll pass the challenge.

As the people said "{" is missing but note that if the user writes the input in lower case or in upper case it ill not work as it should, I would include a new var that converts the input into all upper/lower case and do the if statement. Best regards! :)
