In this case, you know that the example-vector3 library provides a class called Vector3 that accepts three numbers in the constructor, and that has an add method used to add two Vector3 instances together, returning a new instance as the result. The compiler will try to find a .ts, .tsx, and then a .d.ts with the appropriate path. To do this, edit the project tsconfig.json by adding the types property to the compilerOptions option: Now if you go back to your original code, you will see that the error has changed.
