JavaScript JavaScript Basics (Retired) Making Decisions with Conditional Statements Introducing Conditional Statements

Is there a bug? My code seems well structured and returns the correct results but the screen uses a red alert.

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

}

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

if(answer === "Javascript"){

  alert("You are correct");
}

See if you can spot the difference between what I have here and what you have.

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

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

Yes I see the big S in JavaScript but it seems a bit pedantic to check the case of the s in Javascript when the test was about Javascript not typography. The alert fired because I was consistent in using the lower case s. The help code told me to check the === operator.

I understand what you're saying but when writing code the case of letters can matter. If you set a variable as javaScript and then try to refer to it as JavaScript it would say that it's undefined. I too am not great with spelling but when you're in code writing mode, it really can make a difference.

Sorry thanks for the prompt reply, I have moved on. Spelling is not my strong subject.

I started by using toUpperCase but the example fell over. I agree totally but I was testing against what I input. I find it really difficult to parrot and learn. I like to extend and break to learn. Sorry it is just a different style. Yes I have the four S's Syntax Spelling and Simple Steps. I know I spend too much time looking for errors in code and not checking the spelling.

In this example the debugger does not work the actual JavaScript ran as intended.
