The e is the argument of an event handler you attach to a certain event on a certain component... in this case the onFilterTextInput event. Events are objects with certain properties, and e.target almost always represents a DOM element.

Thus e.target.value is the value property of some DOM element, in this case that means the text entered in the search input.

When you need to handle multiple controlled input elements, you can add a name attribute to each element and let the handler function choose what to do based on the value of event.target.name. By React DOC
