# --description--
|
|
|
|
`button1` ist eine Variable, die nicht neu zugewiesen wird. If you are not going to assign a new value to a variable, it is best practice to use the `const` keyword to declare it instead of the `let` keyword. Dadurch wird JavaScript angewiesen, einen Fehler zu melden, wenn du sie versehentlich neu zuweist.
|
|
|
|
Ändere deine `button1`-Variable, so dass sie mit dem `const`-Schlüsselwort deklariert wird.
|
|

|
# --hints--
|
|
|
|
Deine `button1`-Variable sollte mit `const` deklariert werden.
|
|
|
|
```js
|
|
assert.match(code, /const\s+button1/);
|
|
```
|
|
|
|
Deine `button1`-Variable sollte noch immer den Wert deines `#button1`-Elements haben.
|
|
|
|
```js
|
|
assert.deepEqual(button1, document.querySelector("#button1"));
|
|
```
