# if else

Along with that same analogy of asking permission from parents, there was often the or `else` part of it. "You need to clean your room, or else you will be grounded for eternity."

So you really were being given two possible conditions: 1. Room cleaned. 2. Grounded for eternity.

We have the same logic in code with `if else` statements.

## Sample Code

Here's a pretty standard example:

```javascript
var age = 17;
if(age >= 18){
    console.log("You can vote!");
}else{
    console.log("You can't vote");
}
```

If the first condition is true and we are 18 or over, we can vote. The code executes and we're done. If that's not true, execute the code in the `else` block.

## More Sample Code

Copy and paste the following code and play around with running it. Change variables and see what happens:

```javascript
var elevatorUp = true;
var elevatorDown = true;
var elevatorBroken = true;
var elevatorStuckWhileWeAreOnIt = true;
var elevatorNumber = 13;

if (elevatorUp === true) {    //Note: You don't have to have the ===
    console.log("Going up");
} else {
    console.log("Going down");
}  

if (elevatorBroken) {    //Note: You don't have to have the ===
    console.log("Bummer. Let's take the stairs.");
} else {
    console.log("Which floor?");
}  

//Write another one for stuck:
if (elevatorStuckWhileWeAreOnIt){
    console.log("Oh no! We're stuck!");
} else {
    console.log("This elevator is fast.");
}

//But maybe we're standing there waiting?
if(elevatorBroken && elevatorDown){
    console.log("I hope this thing doesn't start flying down!");
} else {
    console.log("How long are you in town for?");
}

if(elevatorBroken || elevatorStuckWhileWeAreOnIt){
    console.log("Hi Bob, this is Bob with maintenance. How can I help?");
}

//Using ints and other types
if(elevatorNumber === 13 && elevatorStuckWhileWeAreOnIt){
    console.log("This is not our lucky day!");
}
```

## Challenges

Pick one or both:

Challenge #1- Write your own conditional with some kind of story or theme like the one above. Make it about whatever you want: football, ponies, trains, etc.

Challenge #2- Fix the bank's bad code:

```javascript
var bankAccount;
var debt = 4200;
var difference = bankAccount - debt;

console.log("I have $" + bankAccount " in my bank account, and I am $" + debt " in debt.");

if ((bankAccount - debt > 700) {
        console.log("I have some extra money. I should pay off my debt. I'll have $" + difference + " leftover.");    
    } else 
        console.log("It probably isn't a good time to pay off my debt.');
}
```
