我有一個現有的對象文字：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."}]}];我正在嘗試動態添加更多對象，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 -???- 嘗試了各種選項，但沒有任何效果。感激地收到建議。
