javascript - 如何重构 "if x return x"语句

Question

我正在寻找重构这种“if x return x”模式的方法。这似乎是多余的。

例如:

async exampleFunction(a) {
    const firstResult = await this.firstHandler(a);

    if (firstResult) {
        return firstResult;
    }

    const secondResult = await this.secondHandler(a);

    if (secondResult ) {
        return secondResult;
    }

    const thirdResult = await this.thirdHandler(a);

    if (thirdResult) {
        return thirdResult;
    }
}

Answer 1

function exampleFunction(a) {
    return this.firstHandler(a) || this.secondHandler(a);
}
