Gereksiz Yeniden Olu\u015fturmalar (Re-renders): React Native Performans\u0131n\u0131n Gizli D\u00fc\u015fman\u0131 Nas\u0131l Ortaya \u00c7\u0131kar ve Nas\u0131l Engellenir?<\/h2>\n React’in temel \u00e7al\u0131\u015fma prensiplerinden biri, kullan\u0131c\u0131 aray\u00fcz\u00fcn\u00fc (UI) verilerdeki de\u011fi\u015fikliklere g\u00f6re otomatik olarak g\u00fcncellemesidir. Bir bile\u015fenin state’i veya props’lar\u0131 de\u011fi\u015fti\u011finde, React bu bile\u015feni ve genellikle t\u00fcm alt bile\u015fenlerini (child components) yeniden render eder. Bu mekanizma, React’i son derece reaktif ve geli\u015ftirici dostu yapar; ancak ayn\u0131 zamanda performans sorunlar\u0131n\u0131n da ana kayna\u011f\u0131 olabilir, zira her render i\u015flemi bir miktar hesaplama g\u00fcc\u00fc gerektirir. E\u011fer bir bile\u015fen, asl\u0131nda hi\u00e7bir verisi de\u011fi\u015fmemesine ra\u011fmen tekrar tekrar render ediliyorsa, bu durum “gereksiz yeniden olu\u015fturma” olarak adland\u0131r\u0131l\u0131r.<\/p>\n
Bu gereksiz re-render’lar \u00e7e\u015fitli senaryolarda ortaya \u00e7\u0131kabilir. \u00d6rne\u011fin, bir \u00fcst bile\u015fen (parent component) state’ini g\u00fcncelledi\u011finde, bu bile\u015fen yeniden render edilir. React varsay\u0131lan olarak, parent bile\u015fen render edildi\u011finde t\u00fcm \u00e7ocuk bile\u015fenlerini de yeniden render eder. E\u011fer bu \u00e7ocuk bile\u015fenlerin props’lar\u0131 de\u011fi\u015fmediyse bile, yine de bu yeniden olu\u015fturma i\u015flemi ger\u00e7ekle\u015fir. Bu, \u00f6zellikle derin ve karma\u015f\u0131k bile\u015fen a\u011fa\u00e7lar\u0131nda, performans \u00fczerinde domino etkisi yaratabilir. \u00d6rne\u011fin, bir ana ekrandaki k\u00fc\u00e7\u00fck bir sayac\u0131n g\u00fcncellenmesi, asl\u0131nda de\u011fi\u015fmeyen bir men\u00fc bile\u015fenini, \u00fcr\u00fcn listesini ve di\u011fer UI \u00f6\u011felerini de yeniden render etmeye zorlayabilir. Bu t\u00fcr senaryolar, performans\u0131 d\u00fc\u015f\u00fcren CPU d\u00f6ng\u00fclerinin israf\u0131na yol a\u00e7ar.<\/p>\n
Bununla birlikte, fonksiyonel bile\u015fenlerde s\u0131kl\u0131kla kar\u015f\u0131la\u015f\u0131lan bir ba\u015fka problem de props olarak ge\u00e7irilen fonksiyon referanslar\u0131n\u0131n her render’da yeniden olu\u015fturulmas\u0131d\u0131r. JavaScript’te, bir fonksiyon her tan\u0131mland\u0131\u011f\u0131nda yeni bir bellek referans\u0131 al\u0131r. E\u011fer bir \u00fcst bile\u015fen her render edildi\u011finde yeni bir fonksiyon tan\u0131mlan\u0131p alt bile\u015fenine prop olarak ge\u00e7irilirse, alt bile\u015fen i\u00e7in bu fonksiyonun “yeni bir prop” oldu\u011fu alg\u0131lan\u0131r ve bile\u015fen gereksiz yere yeniden render edilir. Bu durum, \u00f6zellikle bir \u00fcst bile\u015fenden alt bile\u015fenlere t\u0131klama veya veri g\u00f6nderme gibi olay i\u015fleyicileri (event handlers) ge\u00e7erken performans\u0131 olumsuz etkileyebilir.<\/p>\n
State y\u00f6netim k\u00fct\u00fcphaneleri de bu durumu tetikleyebilir. \u00d6rne\u011fin, Context API veya Redux kullan\u0131l\u0131rken, e\u011fer bir ba\u011flamdaki (context) veya depodaki (store) \u00e7ok k\u00fc\u00e7\u00fck bir de\u011fer de\u011fi\u015firse, bu ba\u011flama abone olan veya store’dan veri \u00e7eken t\u00fcm bile\u015fenler, de\u011fi\u015fen veriyi do\u011frudan kullanmasalar bile yeniden render edilebilir. Yanl\u0131\u015f tasarlanm\u0131\u015f selector’lar veya provider’lar bu t\u00fcr zincirleme re-render’lar\u0131 tetikleyebilir ve performans\u0131n katlanarak d\u00fc\u015fmesine neden olabilir. Bu t\u00fcr senaryolar\u0131 tespit etmek i\u00e7in React DevTools Profiler gibi ara\u00e7lar kullan\u0131labilir; ancak tespit edildikten sonra en etkili \u00e7\u00f6z\u00fcm, genellikle React’in sa\u011flad\u0131\u011f\u0131 memoization mekanizmalar\u0131n\u0131 do\u011fru bir \u015fekilde kullanmakt\u0131r. \u0130\u015fte tam da bu noktada, \u201cSihirli \u00dc\u00e7l\u00fc\u201d devreye giriyor.<\/p>\n
