Write apps like equations!
Code as simple and precise as Mathematical Expressions. Presto is written in PureScript harnessing the powers of Functional Programming & Category Theory. What you get is scalable, performant code with elegant abstractions. Our attempt with Presto is to really simplify the app development process.

## Quickstart
You can get your hands dirty by building a mobile recharge app using Presto
```
git clone https://github.com/juspay/purescript-presto.git
cd purescript-presto/examples/billpay-react

bower i
npm start
```
Open http://localhost:8080/dist/ in your browser.
## Code Snippet
```
billPayFlow :: Flow BillPayFailure StatusScreenAction
billPayFlow = do
_ <- UI.splashScreen
operators <- Remote.fetchOperators
operator <- UI.chooseOperator operators
mobileNumber <- UI.askMobileNumber
amount <- UI.askAmount
result <- Remote.payBill mobileNumber amount operator
UI.billPayStatus mobileNumber amount result
```
