Booleans are just true and false statements. If you put " 3 > 1", the output would be true, because 3 is more than 1 (wow so amazing). ### Booleans Example Below is an example of what a boolean is. This is how they work 
%%js

//You can use these to check your booleans
let keyInserted = true;
let correctKey = false;
let lockPick = true;

if (lockPick) {
    console.log("Door opened.")
}
else {
    //Check if the key you have was inserted and is the correct key
    if (keyInserted){
        console.log("Inserted key into door.")
    }
    else {
        console.log("Insert key into door.")
    }
    if (keyInserted && correctKey){
        console.log("Door opened.")
    }
    else {
        console.log("Incorrect key.")
    }
}
