Muchas gracias!
Muchas gracias!!!
Gracias!
Excelente guía pero tengo una duda, cuando pongo el código en el editor de jsbin me aparece el siguiente mensaje " 'concise methods' is available in ES6 (use esnext option) or Mozilla JS extensions (use moz)" ya probé poniendo esta línea al comienzo del código "/*jshint esnext: true */" pero aun así sigo sin poder renderizar nada en el output. Gracias por la aydua que pueda brindarme, soy nueva en este mundo de react.
Saludos!
