React.js : 초보자 가이드, 시작 위치

React Is A Javascript Library To Build User Interfaces. Think Of It As Simple Web Library That You Can Inject Through <script> Tag.

It Uses Virtual Dom To Handle State And All Its Component And React Based On State Changes. And Updating Virtual Dom Update Browser Dom.

React.createElement(
  'h1',
  {className: 'heading'},
  "hey reader"
)

React Is Just Library And If You Want To Work With Its True Potential You Have To Use Bable To Transpile All JSX into browser-javascript

Above Component In Jsx is littraly

<h1 className='heading'>hey reader</h1>

But You Don't Have To Worry About This Transpiling Things Because All The Framework Build On Top Of React Just Do That Automatically.

For Most Cases React Is Completely Suitable To Work With Because It Provides 1000s' Of Open-Sources Community Library That Is Help To Solve So Many Problems.

But, It Is Recommended To Just See What You Want To Achieve And It Is Too Overkill To Use React In That Scenario.
