so i was reading react.dev's state explanation

when react rerenders due to set function local variable wont be able to maintain its value since it rerenders everything but in its clock or time example where you can input a value on a input element it says that it chooses what to rerender and the value stays intact while the clock is running .
im also assuming that its using a set function to update the clock.

can anyone explain why this is?

Hey everyone,

I have been teaching React JS and building a structured learning path for beginners. I recently created a free React JS Bootcamp by Code ki pathshala where I cover React fundamentals, hooks, projects, and practical development step-by-step through live sessions.

The goal is to help beginners who feel lost while learning React and need a structured roadmap.

I would love feedback from this community — what topics should I improve or add?

Back in spring of 2024 I decided I wanted to learn to code. I decided to take the fullstack course on CodeCademy, which includes react. I got through HTML, CSS, and Javascript, some git stuff, etc. I started react, then I took 9 months off. I've been back at it for about 9 months now (less frequently, as life is much busier now), and when working on react problems I'm finding that I'm really struggling with relatively basic javascript. When working on a react project for the course, I find they will ask me to implement something using javascript, and I often can't even begin. When I turn to google it feels like shooting in the dark, when I ask AI it generally doesn't help very much or it just does it for me. I went to leetcode and tried to do some pretty basic Javascript problems and it feels pretty apparent that I forgot a lot of stuff. I'm in a rather frustrating spot. Does anyone have any advice on what I should do? Is there a specific refresher course or anything like that?

​

TL;DR

Learned HTML, CSS, Javascript, moved into react, took a 9 month break, came back, feel like I can't do diddly-squat, specifically with the Javascript parts. Any advice on refresher courses or anything to get me back up to speed?

One year ago i bought a very expensive course for react claiming that it is the first and last course that i would need. I followed the course and applied with the instructor and everything it was of no use to me as it didn’t remove the ambiguity that i have in my head related to how react works. I’m working on a react project for more than one year but i still struggle with some of the basics and things related to architecture, performance and best practices.
I am just wondering what is the best way to master this library in a free way cause i am no more a beginner but i have some gaps.

Frontend Nation is happening next week and the lineup looks pretty interesting this year.

Lots of talks around frontend architecture, AI workflows, coding agents, React, Vue, Angular, Laravel, performance, and modern tooling.

Speakers include Kent C. Dodds, Aurora Scharff, Alexander Lichter, Ekaterina Sirazitdinova, Steve McDougall, and others from companies like AWS, NVIDIA, Vercel, and VoidZero.

It’s free + online if anyone wants to check it out, I will be joining! https://go.frontendnation.com/fr

One problem I kept hitting: build a Button, then someone needs it as a link. you either copy all the styles to a new component or do something ugly with the html.

Simplest fix is just two components sharing the same styles, that works most of the time.

but if you're building a design system where Button, Card, Text, Heading all need this flexibility, you end up with dozens of variants. that's where polymorphic components come in.

wrote up both approaches:

• when to just use shared styles (the 80% case)
• the as prop pattern for when you need real element flexibility
• asChild (how shadcn/radix does it)
• typescript generics that make it type-safe
• common gotchas

what approach do you use?

Shorter, less jargon, leads with the simple solution first. Better fit for a learning-focused sub.

I have been trying to learn it like for 3 months, I'm following a academind course, but so far it seems like iiiim not learning anything, I'm just rewriting code. i did like 11/30 if the course but I'm not sure if i learned anything, and I want to learn it as quickly as possible. any Ideas, is it possible to do that in 2 months... if so, how?

Need Guidance in React For My Application Frontend

Hey, I am trying to build my first fullstack project, but I really want to implement a nice UI/UX that's modernized but still personalized with the aesthetic that I'm going for. At the moment, it feels like my modal windows open up to plain HTML and CSS and it doesn't feel spicy enough. What do you think I could improve?

Currently, this is what my project looks like.. and I'm not sure how to go about improving it, I just know it needs some work. Is it my general font choice? Is it the decision to use modal windows? Why does this feel outdated to me, yet I can't put my finger on why..

Does anyone have any recommendations of websites that they look at for design inspiration or know of any websites with a nice Table of Contents linked to modal windows?

Hi everyone! 👋 I'm a 19-year-old student currently building my foundation in Data Science and the MERN stack. I got tired of regular, boring to-do list apps, so I decided to build my own interactive goal tracker. Every time I add or complete a daily tech mission, my virtual garden "blooms" with animations! 🦋 My Tech Stack: React Hooks (useState / useEffect) + LocalStorage Pure CSS Animations (@keyframes) Glassmorphism UI design Since I'm still learning and building in public, I would love your feedback! I'm planning to add a Focus (Pomodoro) Timer next. What other features do you experienced devs think I should add? 🤔

Not sure how many people know about this but thought it was worth posting.

Certificates.dev is giving away free React Junior Certification exams for the next 48 hours. .

It's not just multiple choice either, it's also gas code challenges in a structured format, so you're actually proving you can write React, not just recognise it. Was designed with Aurora Scharff who is a well known React expert and speaker so the content is legit.

Covers the fundamentals, components, props, state, JSX, hooks, and event handling. If you've been wanting to validate what you actually know in a meaningful way, now's a good time.

When I first saw hooks like useEffect and useState, they looked simple but confused me when building real projects. Did anyone else go through that stage while learning React?

I am developing a website for a chocolate company. I want the following 3d animation: The candies and chocolates fall from and, piling up on the ground. What library should I use to achieve this effect? Also, I am planning to generate 3d models from images with Meshy AI from renders. I am new to 3d and I want the easiest and cleanest way to do that. I am open to any suggestions.
