    Is it just me or Harry Bhai ne is video me bohot hi High level Tarike se padhaya hai mujhe shuruwaat me thoda dar laga magar mujhe samajh bhi araha tha ke ye kaise kam kar raha hai. What an amazing guy literally the best teacher in the whole world.
    I saw so many videos on web dev most of them were in English but they don't even come close to this level of teaching.
    I love you bro you are improving so many Lives it's amazing.

    1]Components:
    A React component is a modular, reusable piece of the user interface that encapsulates a specific part of the application's logic and view. Components can be either functional or class-based. They allow developers to break down the user interface into smaller, manageable pieces.
    2]States:
    State in React is a built-in object that represents the internal state of a component. It allows a component to keep track of data that can change over time. When the state of a component changes, React re-renders the component to reflect those changes.
    3]Props:
    Props (short for properties) are inputs that are passed to a React component. They allow a parent component to pass data to its child components. Props are immutable, meaning they cannot be modified by the child component.

    Best course ever, even better than paid courses.
    I won't disclose the name but recently I took an online course but didn't find that up to mark then I switched to Sigma course by Harry bhai.
    In short, mene front end yaha se dekha like html css tailwind and now react bhai isse achha koi nahi samjha sakta.
    Mene 2 bar react seekhne ki koshish ki but bahut overwhelming ho jata hai lekin with harry bhai it seems I'll make it this time.
    Thank you from bottom of my heart ❤♥

    13:00 Harry मैने आपकी कई प्लेलिस्ट देखी ,कई जगह मेने हार्स कॉमेंट भी लिखी है इसमें से एक ये थी की कोई भी फंक्शन या कोड लिखो या स्टार्ट करो इससे पहले ये बताया करो की ये इश्यू या ये काम के लिए ये चीज से सॉल्यूशन आयेगा ,लेकिन आप सीधा कोड लिखना चालू करते थे।लेकिन इस वीडियो मे डिटेल में बताया की ये ये कारण है जिसमे React काम आएगा या अच्छी तरह सूट होगा।यही चीज हर वीडियो में करोगे तो लर्नर को जल्दी ख्याल आयेगा।

    Bhai bilkul sahi kaha I made an Billing application with PHP , HTML, JS and CSS aur aaj jab me usme kuch change karna chahta hu to mann hi nahi karta usey choone ka... It was a completely mess aur selectors ka use kar karke paagal ho gaya tha..
    But React seems like using shorttags
    Aur ek baat Harry bhai maine React abhi seekhna shuru kiya hai tumhari videos se bahut maja aa raha hai but 2 doubts hai..??
    1. Kya React se bani website kisi bhi shared hosting pe host ki ja sakti hai ?
    2. iska Backend kya PHP me ho sakta hai, Coz jaha tak mujhe samajh me aaya hai Backend ke liye API ki jarurat paregi, kya PHP me ek API system bana ke use kar sakte hai ?
