What does the following declaration merge between a namespace and a class enable? class Animal { name: string = ”; } namespace Animal { export function create(name: string): Animal { const a = new Animal(); a.name = name; return a; } }

Accepted Answer

The correct answer is A because namespace merging in TypeScript allows adding static-like factory methods to a class without directly modifying its definition. This enables the Animal.create() method to be accessed as if it were part of the Animal class.
