proptypes

> React's [PropTypes], packaged up as a standalone module.

DISCLAIMER:
This is literally copied from the React 0.14 codebase.
If you're using PropTypes with React, it would be silly to reference this standalone version.

Usage

``js
function check(props, propTypes) {
for (let prop in propTypes) {
if (propTypes.hasOwnProperty(prop)) {
let err = propTypesprop;
if (err) {
console.warn(err);
return false;
}
}
}
return true;
}

let valid = check({
a: 42,
b: 'News'
}, {
a: PropTypes.number,
b: PropTypes.oneOf(['News', 'Photos'])
});

valid; // true
`

With webpack:

`js
module.exports = {
resolve: {
alias: {
proptypes: 'proptypes/disabled',
}
}
};

`js
// In
const Baz = (props) => (
