Batch of completions.

This includes: renderMethod where you learn that you can code before the return.

renderIfElse shows you that can use conditions to render a component based on need.

updateLifecycle introduces methods that are called when something is about to be updated, or after it has been updated.
componentWillUpdate() --- componentDidUpdate() --- componentWillReceiveProps(nextProps)

shouldCompenentUpdate can be called to make sure the changes being made should be updated with shouldComponentUpdate(nextProps, nextState)

conciseCondition allows you to add if/else statements in a shorthand inline way { condition && <p>I show up</p>}

ternary uses a ternary if/else statement to render buttons inside the render function --- not a fan.

renderCondition shows you how to use a ternary to send versions of the component based on props.

mapDynRender need to remember that the syntax is different in the render(). Html is normal, and javascript values are in curlies. Wasted a lot of time not paying attention to that.

uniqueKeyAtt.js Talks about the importance of keys as an attribute. It is a way that Reactjs managing changing info.

dynamFilter.js Uses the map() function to manage positive results from the state, and uses filter to then delivir them to component for rendering in a unique key list.

10/23/18 Batch of completions for react redux

extractStateLog.js Managing to make changes to an array through set state without mutating state. Done using a spread operator to shallow copy and concat on the end with a new input.

    setState = {
        messages: [...this.state.messages.concat([this.state.input])];
    }

10/24/18 Batch of react redux

rReducProvider.js I clearly spelled the phonetic version:)
The provider is a Redux wrapper that goes around you app to connect them together.

fullConnectRnR.js This is a full application showing how they work together. It shows you that you when you connect a component with props, and dispacth that it is jsx element that gets rendered as though it was be straight rendered.

const Container = connect(mapStateToProps, mapDispatchToProps)(Presentational);  <===  renders in the app as a component piece.
