Rendering to `document.body` in the examples is conveniently short, but it can
be misleading at the same time, especially for newcomers.
While it's possible to render React components to `document.body`, any 3rd
party scripts can also mess up with it, and it can have unintended consequences
and be source of difficult-to-trace bugs.
Summary:
This section was confusing. I reworded it from:
"JSX is completely optional. You don't have to use JSX with React.
You can create these trees through `React.createElement`. The first
argument is the tag, pass a properties object as the second
argument and children to the third argument."
to:
"JSX is completely optional; you don't have to use JSX with React.
You can create React elements in plain JavaScript using
`React.createElement`, which takes a tag name or component, a
properties object, and variable number of optional child
arguments."
and additionally added another child element to the example code.
Test Plan:
Read the new paragraph!
I kept some places intact (search for @jsx) because they require other bigger changes:
- ref-01-top-level-api.md
- grunt/tasks/npm.js
- old blog posts (don't change those)
- examples/ folder, as they have their own package.json that rely on old dependencies (node-jsx, reactify) that haven't upgraded to 0.12
This will let us keep docs in order on the filesystem but have
reasonable permalinks. If we add something at 02- it doesn't result in
lots of broken links.
