javascript - 如何将 'inject'通用代码应用到各种js函数中？

Question

我正在构建一个测验系统，问题在 JS 中具有通用代码(第二行//more stuff):

 let qId = 1000003, // question ID number, unique to this question
        uId = QWIZM.state.uId,
        sd = QWIZM.methods.toSigDigs,
        stringify = QWIZM.methods.stringify,
        sin = utils.sin,
        cos = utils.cos,
        asin = utils.asin,
        acos = utils.acos,
        tan = utils.tan,
        atan = utils.atan,
        thisQuiz = QWIZM.state.thisQuiz,
        ov = QWIZM.methods.overlayVariable,
        seed = qId > uId ? qId % uId : uId === qId ? uId : uId % qId,
        lcrng = new utils.LCRNG(seed);

// more stuff here

如何插入通用代码，使我的文件看起来像这样:

let qId = 1000003, // question ID number, unique to this question
commonToAll();
// more stuff here

当然，它不一定是一个函数......

您可以使用 ES6 模块来完成此任务。 Mozilla 在 MDN 上有相当全面的解释: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Modules
