Typescript and React setting initial state with empty typed array

Question

Say I have the following snippet:

interface State {
  alarms: Alarm[];
}
export default class Alarms extends React.Component<{}, State> {
  state = {
    a         


        

Answer 1

Declaration:

alarms: Array

Initialization in state :

this.setState({
var1:'',
var2:''
});

I prefer the above declaration
