# --description--
The `condition` string is just a placeholder. Change the `if` statement condition to check if `gold` 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) {
}
```
# --hints--
Your `if` statement should check if `gold` is greater than or equal to `10`.
```js
assert.match(buyHealth.toString(), /if\s*\(gold\s*>=\s*10\)/);
```
Your `buyHealth` function should update `health` and `gold` if `gold` is greater than or equal to `10`.
```js
gold = 10;
health = 10;
buyHealth();
assert.equal(health, 20);
assert.equal(gold, 0);
const healthElement = document.getElementById('healthText');
assert.equal(healthElement.innerText, '20');
const goldElement = document.getElementById('goldText');
assert.equal(goldElement.innerText, '0');
```
Your `buyHealth` function should not update `health` and `gold` if `gold` is less than `10`.
```js
gold = 5;
health = 10;
buyHealth();
assert.equal(health, 10);
assert.equal(gold, 5);
```
