### Interacting with contracts in Javascript
Embark will automatically take care of deployment for you and set all needed JS bindings. For example, the contract below:
```
// app/contracts/simple_storage.sol
contract SimpleStorage {
uint public storedData;
function SimpleStorage(uint initialValue) {
storedData = initialValue;
}
function set(uint x) {
storedData = x;
}
function get() constant returns (uint retVal) {
return storedData;
}
}
```
Will automatically be available in Javascript as:
```
// app/js/index.js
import SimpleStorage from 'Embark/contracts/SimpleStorage';
SimpleStorage.methods.set(100).send();
SimpleStorage.methods.get().call().then(function(value) { console.log(value) });
SimpleStorage.methods.storedData().call().then(function(value) { console.log(value) });
```
The syntax used is <a href="https://web3js.readthedocs.io/en/v1.2.1/" target="_blank">web3.js 1.2.1</a>
