A simple question regarding conditional statements and defining variables

I'm wondering 1. why the console is throwing out a specific result 2. how to get the console to throw out the result I want based on the code

I've tried both removing the else condition and adding it, but I'm stuck because I don't know what the code is thinking. 

isMarried = false; 
if (isMarried = false) {
    isMarried = 'Nope, not at all! ';
} 

console.log(firstName + ' is a ' + age + ' year old ' + job + '. Is he married? ' +isMarried );


//This outputs false for isMarried instead of "Nope, not at all!" 

If I add an else like so: 
 if (isMarried = false) {
    isMarried = 'Nope, not at all! ';
} else {
    isMarried = 'Oh yeah';
}

//The same code outputs "Oh yeah." I'm a bit confused why it's happening like this. Any thoughts? 

Basically, I expected the computer to see isMarried as a false boolean, and if this is the case, I wanted to set the variable to the string seen above. Otherwise, if I changed it to true, for example, the it would be a different string.

You are assigning a value to your isMarried(false) inside the IF statement .. you need to use compare operators like ==

a == b // this operator will return a `Boolean` value (`true` Or `false`)
a = b  // this operator will return the value of `b` (right value)

So :

isMarried = false  // this will return the right value (false) which means the IF statement
                   // won't work and the else code will be auto executed

You don't use assignment operators (=) inside conditionals. Inside conditionals, you need to use comparison operators (==, !=, >=, <, etc.)
