# --description--
`button1` is a variable that is not going to be reassigned. 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. This will tell JavaScript to throw an error if you accidentally reassign it.
Change your `button1` variable to be declared with the `const` keyword.
# --hints--
Your `button1` variable should be declared with `const`.
```js
assert.match(code, /const\s+button1/);
```
Your `button1` variable should still have the value of your `#button1` element.
```js
assert.deepEqual(button1, document.querySelector("#button1"));
```
