# --description--
Anonymous functions are functions without names - they are used only once and then forgotten. The syntax is the same as for normal functions but without the name:
```js
function(x) {
return x
}
```
First, remove the `addVar` definition.
# --hints--
See description above for instructions.
```js
assert(!code.replace(/\s/g, '').includes('constaddVar=add'));
```
