# --description--
Provide the number zero as the initial value of the `reduce()` method by passing it as the second argument.
Here is an example of a `reduce()` method with an empty object as its initial value:
```js
arr.reduce((accumulator, currentValue) => {
/* code to run */
}, {});
```
# --hints--
See description above for instructions.
```js
assert(
code
.replace(/\s/g, '')
.match(
/reduce\(\(accumulator\,currentValue\)\=\>\{\/\*codetorun\*\/\}\,0\)/
)
);
```
