Why doesn't this form code work? It seems logical - forms

Question

I'm trying to program a simple form that asks for the following inputs:
mood, age, and gender
It does not matter what I put in the mood prompt. It always comes out positive. For the age, I would like the tab to close if they are under 18 years old. For gender, it goes the same with the mood prompt. Any help would be appreciated.
var userMood = prompt("Hey! How's it going?");
if (userMood = "good" || "Good") {
alert("Awesome! We just need you to fill out a form for security reasons.");
} else if (userMood != "good" || "Good") {
alert("Oh, I'm sorry to hear that... We just need you to fill out a form for security reasons.");
}
var userAge = prompt("What is your current age?");
if (userAge >= "18" ) {
alert("Great! You are the sufficient age to enter this webpage!");
userAge = true;
} else if ( userAge <= "17"){
alert("Sorry, you are too young to view this content...");
window.close();
}
var userGender = prompt ("What is your gender?");
if (userGender = "male" || "Male" || "female" || "Female"){
alert("Great! You're human!");
userGender = true;
} else {
alert("The webpage has perdicted non-human cyber activity, you can no longer continue.");
window.close();
}

Answer 1

i'm going to make my answer verbose to help you learn. for starters, you are using = when you mean to use == or even ===. this is why the mood is always registering as good, because userMood = "good" sets userMood to 'good' and so the expression evaluates to "good", which validates the if statement because FALSE for strings is "" and true is every other string. also userMood = "good" || "Good" doesn't do what you think it does. you need to check both strings like so (userMood === "good" || userMood === "Good").

Answer 2

I tried varying some lines in your code into something below.
var userMood = prompt("Hey! How's it going?");
if (userMood == "good" || userMood == "Good")
alert("Awesome! We just need you to fill out a form for security reasons.");
else
alert("Oh, I'm sorry to hear that... We just need you to fill out a form for security reasons.");
var userAge = prompt("What is your current age?");
if (userAge >= 18 )
{
alert("Great! You are the sufficient age to enter this webpage!");
userAge = true;
}
else if ( userAge < 18 && userAge > 0)
{
alert("Sorry, you are too young to view this content...");
window.close();
}
else if ( userAge < 0 )
{
alert(" ***** prompt message for inputting negative number ****");
window.close();
}
var userGender = prompt ("What is your gender?");
if (userGender == "male" || userGender == "Male" || userGender == "female" || userGender == "Female")
{
alert("Great! You're human!");
userGender = true;
}
else
{
alert("The webpage has perdicted non-human cyber activity, you can no longer continue.");
window.close();
}
