Nullcheck on nullable Types in Typescript

Question

I'm new to typescript, with the following code interface definition.

export Interface Response {
  content?: {
    // ...
  }
}

let response: Response | null = something();

How to access content without doing null checks, which i assume is not at all the best approach.

if (response != null) {
  if (response.content != null) {
    content = (response.content as MyContent);
  }
}

Answer 1

content = response?.content == null ? null : response.content as MyContent;
