- Pulled create-react-class out of react.
- Extended functionality to work for React.PureComponents and React.Component.

Why to use this module.

create-react-class requires you to change the way you use React.
Forget about getInitialState or getDefaultProps.
Just use state like you normally would and when the react class gets created well initialize the state for you.

`` js
const Obj = {
create(props) {
this.state = {
header: null
}
},
componentDidMount() {},
componentDidUpdate() {},

render() {

}
};
`

We also handle static functions like getDerivedStateFromProps for you so just define it like you would any function. no need to place it inside a statics variable.
` js
Obj.getDerivedStateFromProps = (props, state) => {

}
`

Other Modules

- @mavega/oloo
- Helps with inheritance of Objects.
- @babel/plugin-transform-react-display-name
- It can help with errors that occur. The name of the Object will show in Stack Trace.

Vscode Extensions

- JavaScript to Typescript Converter & Syntax Highlighter
- Help with AutoComplete in vscode for React methods.
- Helps with inheritance when using plain Objects.
- Provides Linting of Objects for CreateReactClass.
- JS/React Snippet Extension.

Speed

Same speed, sometimes its more, sometimes its a little less.

For Comparison a typically Class takes less than 100 milliseconds to create 1 million times.

// displayName also works and is ideal.

* @returns {InputModalType}
*/
create(props) {
// This sets up a chain of prototypes that will be assigned to a new react instance.
// Extremely Basic jist is Object.setPrototypeOf(inputModal, baseModal);
// input.__proto__ === InputModal
// input.__proto__.__proto__ = BaseModal
// We will keep this chain on the react class instance so base methods can be used later on.
const inputModal = Oloo.assign(BaseModal.create(), InputModal);

// This will get overwritten by the assignment(inputModal.modalStyle) below. We take all the variables added to the inputModal and assign them to the react instance.
// If you only want to use 'this' then make sure you call create of child like so.
// BaseModal.create.call(this, arg0, arg1)
this.modalStyle = {};
this.index = null;

* Calling props like this will work even it its not in default props.

/**
* You can't access an obj on props if it is not defined in defaultProps.
*/

// Use it like above.

/**
* @description Boolean that determines whether we are showing this modal.
*/

};

export const InputModalObject = InputModal;
export default createReactPure(InputModal, optionalOptions);
`

` js
import InputModal from 'SRC/InputModal';

// Now you can use it like any React Component.
