# Utility for ordering pair of assets in (amount_asset, price_asset)
![Build Status](https://api.travis-ci.org/wavesplatform/assets-pairs-order.svg?branch=master)
## Accepts:
```javascript
orderPairs(string, string)
orderPairs([string, string])
orderPairs([string, string], [string, string], ...)
orderPairs([[string, string], [string, string], ...])
```
## Returns:
```javascript
[
[amount_asset1, price_asset1],
[amount_asset2, price_asset2],
...
]
```

You can redefine `predefinedList` property:
(By default it's MAINNET_DATA)
```javascript
import orderPairs from '@waves/assets-pairs-order';
orderPairs.predefinedList = ['2', '1'];
orderPairs([['1','2']])
/* [
[
'1',
'2',
]
]
