使用SLF4J結合Logback或Log4j2是Java應用中配置日誌的推薦方式，通過添加對應Maven依賴引入API和實現庫；2.在代碼中通過SLF4J的LoggerFactory獲取日誌記錄器，使用參數化日誌記錄方法編寫解耦且高效的日誌代碼；3.通過logback.xml或log4j2.xml配置文件定義日誌輸出格式、級別、目標（控制台、文件）及包級別的日誌控制；4.可選啟用配置文件掃描功能實現日誌級別的動態調整，SpringBoot中還可通過Actuator端點管理；5.遵循最佳實踐，包括

在JavaScript中，向數組開頭添加元素最常用的方法是使用unshift()方法；1.使用unshift()會直接修改原數組，可添加一個或多個元素，返回添加後的數組新長度；2.若不想修改原數組，推薦使用擴展運算符（如[newElement,...arr]）創建新數組；3.也可使用concat()方法，將新元素數組與原數組合併，返回新數組且不改變原數組；綜上，修改原數組時用unshift()，保持原數組不變時推薦擴展運算符。
