const App = () => {
  
  // Create collection
  const my_collection = Pleex.collection('myCollection');
  
  // Get all data saved
  my_collection.getItem(
    { age: 12 },
    (data) =>  // data can access here,
    (error) => alert(error)

## Tips:

1. if many items exists and matches with object you provide, getItem only return the last matched one.
2. to get list of matched items use [getItems](https://pleex.gitbook.io/docs/getitems).
3. if pleex don't find anything its return **undefined**
