1st task becomes broken when trying to check the third step.

I have written this code three times and have watched the video the same amount. Not sure if I am making a syntactical mistake for the variable creation or the conditional statement. The first 2 tasks get checked and work fine but when I add the else clause then it says that my Task 1 no longer works.

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

if (answer === "JavaScript") {
  document.alert("You are correct")
} else {
 document.alert("JavaScript is the best language!") 
}
index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <title>JavaScript Basics</title>
</head>
<body>
<script src="app.js"></script>
</body>
</html>

Hi Ben,

Rather than document.alert just use alert. It is also good practice to finish each line with a semicolon ;.

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

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

Yo Damien!

When writing inline code, use the back tick (`) instead of the single quote ('). On that note, the valid syntax for JavaScript is ```javascript not ```js.

Check out this handy post!

Cheers!

Hi Rich, Good to know. Oh, I wasn't trying to write inline code just highlighting the word, didn't know you could... haha.

Both 'js' and 'javascript' seem to be valid? Also 'objc' works but is not listed.

var test = "js";

var test = "javascript";

id test = "objc";
