Typescript -函数应返回字符串，而不是() ->字符串

function getString(): string {
    return "Hello, World!";
}

const result: string = getString();
console.log(result); // 输出: Hello, World!

function getStringFunction(): () => string {
    return () => "Hello, World!";
}

const resultFunction: () => string = getStringFunction();
const result: string = resultFunction();
console.log(result); // 输出: Hello, World!

function generateString(name: string): string {
    return `Hello, ${name}!`;
}

const result: string = generateString("Alice");
console.log(result); // 输出: Hello, Alice!

const getString = (): string => {
    return "Hello, World!";
};

const result: string = getString();
console.log(result); // 输出: Hello, World!

const getStringFunction = (): (() => string) => {
    return () => "Hello, World!";
};

const resultFunction: () => string = getStringFunction();
const result: string = resultFunction();
console.log(result); // 输出: Hello, World!
