Aug 05, 2025 am 07:48 AMJavaScript提供多種創(chuàng)建對象的方法,應(yīng)根據(jù)需求選擇:1.對象字面量適用于簡單的單例對象;2.構(gòu)造函數(shù)適合創(chuàng)建多個結(jié)構(gòu)相同的實例;3.ES6類提供更清晰的語法并支持繼承;4.Object.create()可精確設(shè)置原型;5.工廠函數(shù)通過返回對象實現(xiàn)靈活創(chuàng)建;此外,Object.assign()可用于合并或克隆對象,最終選擇應(yīng)基于具體使用場景和編碼風(fēng)格。
Aug 05, 2025 am 07:45 AMChrome的實用程序進程負責(zé)處理與網(wǎng)頁或擴展無關(guān)的系統(tǒng)級任務(wù),例如管理下載、處理剪貼板訪問、運行網(wǎng)絡(luò)堆棧等。1.它將不同類型的實用任務(wù)隔離,以提高安全性和性能,如分別處理網(wǎng)絡(luò)、GPU和音頻相關(guān)任務(wù)。2.多個實用程序進程同時運行是正?,F(xiàn)象,每個進程獨立工作,防止一個問題導(dǎo)致整體崩潰。3.如果某個實用程序進程占用資源過高,可能是臨時操作引起,如下載大文件,若持續(xù)高占用,可嘗試重啟瀏覽器、檢查擴展或更新Chrome。
Aug 05, 2025 am 07:43 AMstd::source_location是C 20引入的用于獲取源碼位置信息的類,1.可通過std::source_location::current()在編譯時獲取文件名、行號、函數(shù)名等信息;2.常用于日志、調(diào)試和錯誤報告;3.與宏結(jié)合可自動捕獲調(diào)用位置;4.function_name()可能返回mangled名稱,需配合abi::__cxa_demangle解析以提升可讀性;5.所有信息在編譯時確定,運行時開銷極小,適合集成到日志或測試框架中以提高調(diào)試效率。
