Encountered some variables that are not defined but are being used in the code. This would give potential errors that will break the code. It might have happened because of a typing mistake. Please review the occurrences and make sure the names are correctly mentioned.

Potential ReferenceErrors may result from misspellings of variable and parameter names, or accidental implicit globals (for example, forgetting the var keyword in a for loop initializer).

Bad Practice

<Hello name="John" />;

// will ignore Text in the global scope and warn
var Hello = React.createClass({
  render: function() {
    return <Text>Hello</Text>;
  }
});
module.exports = Hello;

Recommended

var Hello = require('./Hello');

<Hello name="John" />;
