HTML Versus XHTML

XHTML is a stricter, more XML-based version of HTML.
What is XHTML?
XHTML stands for EXtensible HyperText Markup Language
XHTML is a stricter, more XML-based version of HTML
XHTML is HTML defined as an XML application
XHTML is supported by all major browsers
Why XHTML?
XML is a markup language where all documents must be marked up correctly (be "well-formed").
XHTML was developed to make HTML more extensible and flexible to work with other data formats (such as XML). In addition, browsers ignore errors in HTML pages, and try to display the website even if it has some errors in the markup. So XHTML comes with a much stricter error handling

Handling Events

Handling events with React elements is very similar to handling events on DOM elements. There are some syntax differences:
React events are named using camelCase, rather than lowercase.
With JSX you pass a function as the event handler, rather than a string.
