## Description
< section id = 'description' >
The word "condition" inside the if statement is just a placeholder. Change the condition to check if the amount of gold the player has is greater than or equal to 10.
Here is an `if` statement that checks if `num` is greater than or equal to 5:
```js
if (num >= 5) {
2020-01-29 15:13:18 +09:00
console.log("Num is greater than or equal to five!");
2019-11-05 10:56:32 +09:00
}
```
