Question

which of the following shows the correct way to set up a variable called houses in JavaScript

Answer 1

In JavaScript, you can set up a variable called `houses` using either `var`, `let`, or `const`, depending on the intended scope and mutability of the variable. Here are the different ways you can set it up:

1. Using `var`:
```javascript
var houses;
```

2. Using `let` (if you plan to reassign the variable later):
```javascript
let houses;
```

3. Using `const` (if you intend for the value to remain constant and not be reassigned):
```javascript
const houses = [];
```

4. If you want to initialize `houses` with some data (like an array or an object), you could do:
```javascript
let houses = []; // Empty array
```

or

```javascript
const houses = { /* some properties */ }; // Object
```

Choose the appropriate method based on how you want to use the `houses` variable in your script.
