If you type false in the condition it appears "the condition is false". I don't understand, why and how?

Because when you pass the boolean in the condition it's always going to return true or false.

Example:

  if(false){
  console.log('true');
}else{
  console.log('false');
}

The above example is always going to return false because we are asking whether it's false or not.

Now see the below example I made this the other way around.

if(true){
  console.log('true');
}else{
  console.log('false');
}

This is going to return true because we are checking whether it's true or not.

Go ahead and feel free to play around with these.

I'm not following this either, so is "if" always tied to the true return from the boolean?

Otherwise if it were just like any other if-else, the if statement would be satisfied (in the first example) and return 'true', right? The way I read the first example is, if the boolean return is false - log 'true', else log 'false'
