javascript - 如何将具有数组键的对象动态添加到对象文字？

Question

我有一个现有的对象字面量:

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."}
]
}

];

我正尝试按如下方式动态添加更多对象:

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。非常感谢您的建议。

为什么不采用完整的对象进行推送并将 nextwordSentencesArray 与所需属性进行映射？

words.push({
    word: "nextword",
    definition: "nextword definition",
    examples: nextwordSentencesArray.map(sentence => ({ sentence }))
});
