Providing default value for prop function in React

Question

What is the best way to handle additional React.PropType.func properties?

Should I provide a default noop for it (if this is the best way) or should I just check if support is defined?

 propTypes: { onClick: React.PropTypes.func }, someMethod: function() { if (this.props.onClick) { this.props.onClick(); } } 

Answer 1

React has getDefaultProps . Then you can call onClick without errors.

 getDefaultProps: function() { return { onClick: function() {} }; } 

Answer 2

You can do with typeof :

 if (typeof this.props.onClick === 'function'){ //... }
