javascript - React error "Uncaught TypeError: type.toUpperCase is not a function" on a hello world app -
i have started dabbling reactjs, , on following tutorial , got error on title, on running simple hello world app. below single page code have:
<!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <title>document</title> <script src="https://fb.me/react-0.13.3.js"></script> <script src="https://fb.me/jsxtransformer-0.13.3.js"></script> </head> <body> <script type="text/jsx"> // define class var helloworld = react.createclass({ render: function() { return <div> hello world! </div> } }); // create element class var element = react.createelement({helloworld}); // render class , place in body tag react.render(element, document.body); </script> </body> </html> any hints or resolution appreciated.
there mistake in following line:
var element = react.createelement({helloworld}); it should be:
var element = react.createelement(helloworld); notice lack of curly braces.
