-#### `React.FunctionComponent<P>` or `React.FC<P>`

 Type representing a class component
 ```tsx
 class MyComponent extends React.Component<Props, State> { ...

-#### `React.ComponentProps<typeof Component>`
-Gets type of Component Props, so you don't need to export Props from your component ever! (Works for both FC and Class components)
-```tsx
-type MyComponentProps = React.ComponentProps<typeof MyComponent>;

-#### `React.ComponentType<P>`
-Type representing union type of (React.FC | React.Component)
+#### `React.ComponentType<Props>`
+Type representing union of (React.FC<Props> | React.Component<Props>) - used in HOC
 ```tsx
 const withState = <P extends WrappedComponentProps>(
   WrappedComponent: React.ComponentType<P>,
 ) => { ...

-#### `React.ReactElement` or `JSX.Element`
+#### `React.ComponentProps<typeof XXX>`
+Gets Props type of a specified component XXX (WARNING: does not work with statically declared default props and generic props)
+```tsx
+type MyComponentProps = React.ComponentProps<typeof MyComponent>;

+
+#### `React.ReactElement` | `JSX.Element`
 Type representing a concept of React Element - representation of a native DOM component (e.g. `<div />`), or a user-defined composite component (e.g. `<MyComponent />`)
 ```tsx
 const elementOnly: React.ReactElement = <div /> || <MyComponent />;

+
+<Input about={...} accept={...} alt={...} ... />

 ```
 
-#### `React.MouseEvent<E>` | `React.KeyboardEvent<E>` | `React.TouchEvent<E>` etc...
-Type representing more specific event handler
+#### `React.XXXEvent<HTMLXXXElement>`
+Type representing more specific event handler. Some common event examples: `ChangeEvent, FormEvent, FocusEvent, KeyboardEvent, MouseEvent, DragEvent, PointerEvent, WheelEvent, TouchEvent`.
 ```tsx
 const handleChange = (ev: React.MouseEvent<HTMLDivElement>) => { ... }
