# ReactPy
[ReactPy](https://reactpy.dev/) is a library for building user interfaces in Python without Javascript. ReactPy interfaces are made from components that look and behave similar to those found in [ReactJS](https://reactjs.org/). Designed with simplicity in mind, ReactPy can be used by those without web development experience while also being powerful enough to grow with your ambitions.

# At a Glance
To get a rough idea of how to write apps in ReactPy, take a look at this tiny _Hello World_ application.
```python
from reactpy import component, html, run
@component
def hello_world():
return html.h1("Hello, World!")
run(hello_world)
```
