The Curly Braces Object
Explore how to define and use object literals with curly braces in TypeScript. Understand the advantages of structural typing, correctly specifying object types, and the potential pitfalls of casting. This lesson helps you organize data efficiently and avoid runtime errors when working with objects.
We'll cover the following...

TypeScript can create an object using the curly braces – it is an object literal like in JavaScript. The limitation is that you must define every member at initialization time.
The advantage is that it’s a quick way to organize data. It’s also a natural way to organize data coming from a JSON Payload. For example, executing a request to receive a payload will provide you with a literal object.
TypeScript is a structural language and does not need to have a name. This works great for cases where you do not need to map all the data to a type. With a structural type, you can cast the data and have the structure mapped for you ...
