Prefer using self closing instead of closing tag for components having no children JS-0468

Components without children can be self-closed to avoid the unnecessary extra closing tag. In JSX, closing tags are required when the component has children example <MyComponent>...</MyComponent> and if there are no child component between these tags, then this component can be self closed using <MyComponent />. It is recommended as it improves readability, and it is more compact to use self-closing for these types of components.

Bad Practice

var HelloJohn = <Hello name="John"></Hello>;

var HelloJohnCompound = <Hello.Compound name="John"></Hello.Compound>;

Recommended

var HelloJohn = <Hello name="John" />;

var HelloJohnCompound = <Hello.Compound name="John" />;
