Fatih Soysal burada. Bug\u00fcn Javascript'te asenkron programlaman\u0131n inceliklerine dalaca\u011f\u0131z. Bildi\u011finiz gibi, Javascript tek i\u015f par\u00e7ac\u0131kl\u0131 (single-threaded) bir dildir. Bu, bir seferde sadece bir g\u00f6rev yapabilece\u011fi anlam\u0131na gelir. Ancak, bir\u00e7ok web uygulamas\u0131 a\u011f istekleri, dosya okuma gibi zaman alan i\u015flemler gerektirir. \u0130\u015fte burada asenkron programlama devreye giriyor; uygulaman\u0131z\u0131n bu i\u015flemler bitene kadar donmas\u0131n\u0131 engelliyor ve di\u011fer g\u00f6revleri yapmaya devam etmesini sa\u011fl\u0131yor."}
