# --description--
The array destructuring syntax can be used to extract values from arrays:
```js
const [x, y] = [1, 2]; // in variables
const fn = ([x, y]) => x + y // in functions
```
Use this syntax to define a function `random` in `spreadsheetFunctions` which takes the array `[x, y]` and returns `x`.
# --hints--
See description above for instructions.
```js
assert(
/["']?random["']?:\(\[x,y\]\)=>x/.test(code.replace(/\s/g, '')) &&
spreadsheetFunctions['random']([1, 2]) === 1
);
```
