Declaring a sophisticated array as a property within another property in Typescript

As a newcomer to Angular and Typescript, I am facing a challenge while declaring a property with a complex array as one of its values. Here is what I have attempted:

groupedItem: {
     customGroupId: string,
     cgName: string,
     category: [{ 
    customGroupItemId: string,
     name: string }]
 };

But when I try to access the property 

this.groupedItem.category.name

An error message pops up saying

Property 'name' does not exist on type '[{ customGroupItemId: string; name: string; }]'

It seems like the 'name' property is there. Any idea what mistake I might be making?

Answer №1

Upon careful examination of the object named groupedItem, it becomes evident that the property category is actually an array rather than an object. To access it, you must use the following code:

this.groupedItem.category[0].name
