如何将带有数组键的对象动态添加到对象字面量？

Question

我有一个现有的对象文字：var words=[    {"word":"callous","definition":"uncaring","examples": [   {"sentence":"How could you be so callous?"},   {"sentence":"What a callous thing to say!"},   {"sentence":"That showed a callous disregard for the consequences."}]}];我正在尝试动态添加更多对象，如下所示：var obj={};obj.word="nextword";obj.definition ="nextword definition";obj.examples= ???;for (var i = 0; i < nextwordSentencesArray.length; i++) { ??? obj.examples.sentence.push(nextwordSentencesArray[i]);}words.push(obj);我在 -???- 尝试了各种选项，但没有任何效果。感激地收到建议。

为什么不使用完整的对象进行推送和nextwordSentencesArray与所需属性的映射？

words.push({

    word: "nextword",

    definition: "nextword definition",

    examples: nextwordSentencesArray.map(sentence => ({ sentence }))

});
