If you have a lot of props you don't want in ...rest e.g. defaultProps, it can be annoying to write all of them twice. Instead you can create it yourself with a simple loop over the current props like that:

let rest = {};
Object.keys(this.props).forEach((key, index) => {
    if(!(key in MyComponent.defaultProps))
       rest[key] = this.props[key];
});
