如何动态地将带有数组键的对象添加到对象文字？

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);

我曾在-???-尝试过各种选项，但没有任何效果。感激之至。

为什么不采用完整的对象进行推送以及nextwordSentencesArray具有所需属性的映射？

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