سوال من در مورد useEffect می‌باشد.با توجه به قطعه کد زیر
کنسولی که در useEffect نوشته شده است مقدار `{}`را نشان میدهد ولی در `return` مقدار `{ name: "Alex", class: "4" } `.چرا؟
import React, { useState, useEffect } from "react";
import "./styles.css";
export default function App() {
const initData = {
name: "",
class: ""
};
const condition = true;
const exampleData = { name: "Alex", class: "4" };
const [currentStudent, setCurrentStudent] = useState({});
const [formData, setFormData] = useState({});
useEffect(() => {
setCurrentStudent(exampleData); // My example code to setState
//The result of currentStudent is {name: "Alex", class: "4"}
setFormData(condition ? exampleData : initData);
console.log("useEffect =", formData);
}, []);
return <>{console.log("ui = ", formData)}</>;
} برای دمو .

Continuing our series on the over 100 API changes in .NET 6, we look at extensions to the LINQ library.
Here's a couple of final thoughts.
- 3 major front end frameworks (Angular, React, and Vue)
- React is the highest growing and highest paying front end framework
- Express is still the dominant Node framework by far
- TypeScript is becoming more and more popular (and it's going to take over...just my thought)
- Tooling is making JavaScript a more evolved and appealing language
- Options to reach almost any platform (desktop, mobile, server, web, hybrid, etc.)
- Graphql is on the rise, especially with the rise of Gatsby.js
- چون date picker ای که در حال استفاده هستید، سورس باز واقعی نیست و فشرده شده، نتوانستید کدهای آن‌را مطالعه کنید. قطعه کد PersianDatePicker.Show مربوط به مطلب جاری هست و ارتباطی به سایر تقویم‌ها ندارد و اصلا معادلی در date pickerهای دیگر ندارد.
- برای سایر تقویم‌ها onclick را حذف کنید. اگر خودش onchange دارد، از آن همان استفاده کنید و نیاز به تغییر دیگری ندارد (نیازی به addEventListener ندارد). یعنی کدهای window.CallAmib همان enableDatePicker می‌شوند (البته فقط قسمت objectReference.invokeMethodAsync آن نیاز است). بنابراین بسته به اینکه کدام را می‌خواهید صدا بزنید، سطر فعالسازی آن باید تنظیم شود.
