javascript - 将不正确的变量类型传递给函数不会发出类型错误(Passing incorrect variable type to function do not emit type error)

Question

Can you explain why when I pass incorrect variable type to the function ts do not emit type error?

(您能解释为什么当我将错误的变量类型传递给函数ts时不会发出类型错误吗？)

export class CreateCategoryDto implements Omit<Category, 'id' | 'children' | 'parent'> {
  name: string;

  parentId: number;
}

export async function createCategory(dto: CreateCategoryDto) {
  return getRepository(Category).save(dto);
}

const data = { id: 555, name: 'sdfsdf', parentId: 55 };
ctx.body = {
    data1: await createCategory(data), // not emit
    data: await createCategory({ id: 555, name: 'sdfsdf', parentId: 55 }), // emit that params must be without id
  };
