I have an object which has the following entry in it:
numberOfReturns: number = 0;
returns_explanations: string [] = [];
departure_time: string = '';
arrival_time: string = '';
So in departure_time i have the following information:
...
departure_time: 08:15
departure_time: 08:02
departure_time: 09:00
...
I have an array of this whole object which will need to be iterated and i need to get the average departure_times.
let average: Date = null;
for (let i = 0; i < workAccountItem.length; i++) {
average = moment(average).add(moment('01/01/2021 ' + workAccountItem[i].departure_time));
}
average = average / workAccountItem.length;
This approach won't work.
In your main type interface, it looks like you have an extra space between string and [] for returns_explanations -- if you're defining a prop as having a type array of strings, it should be string[] with no space. For your type definition for average, you can also set it to being either Date or null like so, average: Date | null, which will prevent type errors when no date is present yet.
