What is the correct type for 'e' as in uploadImage function parameter?
public uploadImage(e /* :type of e */){
const image = e.target.files[0];
const reader = new FileReader();
reader.readAsDataURL(image);
reader.onload = e =>{
this.previewImage = e.target.result;
console.log(this.previewImage);
};
}
In template I have this
<input type="file" accept="image/jpeg" @change=uploadImage>

An Event Bus is nothing but a global Vue instance that is imported by the components involved in communication and passing data. It makes use of the $on, $emit, and $off properties of the Vue object to emit out events and pass on data.
Components are reusable Vue instances with custom HTML elements. Components can be reused as many times as you want or used in another component, making it a child component. Data, computed, watch, and methods can be used in a Vue component.
Vue takes an approach similar to the HTML DOM events. An element will "emit" an event and the data from that event. This is a robust way to handle custom events because we know that a child component has inputs (props) and outputs (custom events).
The type is just Event. Relevant information is on e.target property.
