Topic

Technology — a classification, not a measurement. An on-box language model (Qwen3.6-35B-A3B-FP8, prompt version 1) read this channel’s own recent posts on 21 September 2026 and assigned it the closest of 31 fixed categories, at 52% confidence. This is a model’s judgement about what the channel is likely to be about, not a fact this register measured the way a subscriber count or a view count is measured — it can be revised on a later pass, and it carries no weight anywhere else on this page. How this classification works, and why it has no browse page of its own yet.

7 measurements spanning 43 days, net -15. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 498–517 and does not start at zero.

Engagement

20 posts held, back to 23 April 2025the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 1 page of Telegram’s post history, 20 posts per page.

Nothing published in the last 30 days. ERR and ER are rolling 30-day measures, so there is nothing to compute — we hold 20 posts for this entry, the most recent from 29 September 2025. An engagement rate over an empty window would be a number about nothing.

Reaction mix

61 reactions across 18 posts, in 3 distinct kinds. The most used accounts for 95.1% of them.

Every reaction kind recorded on the sample, most used first

No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.

Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.

Coverage. Reactions were read on 18 of the 20 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 61 reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.

Measured over the 20 most recent posts we hold, published 23 April 2025 to 29 September 2025, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

Фронтендеры, всем привет. 👋 Итак, затянулся сентябрь, но посты на 1.10 уже отгружены, скоро снова начнем вам давать знания по фронтенду. У меня к вам 2 вопроса: 1. Какие бы вы хотели увидеть обновления в контенте на канале? Так как за более чем 6 месяцев мы испробовали разные варианты. 2. Кто из вас уровня мидл+ и сеньор, и интересно преподавание фронтендерам? Мои друзья сейчас в поиске спецов умеющих объяснять с

Нашел кейс, где компонент не обновляется при изменении данных. В чем проблема? // Кастомный хук для получения данных пользователя function useUserData(userId) { const [userData, setUserData] = useState(null); useEffect(() => { let isMounted = true; const fetchData = async () => { const response = await fetch(`/api/users/${userId}`); const data = await response.json(); if (isMounted)

Push-уведомления давно стали неотъемлемой частью веб-приложений. С помощью Web Push API можно отправлять уведомления даже когда пользователь не находится на сайте. Для реализации push-уведомлений нам понадобится:// 1.

В последнее время активно использую новые PWA API, которые существенно расширили возможности веб-приложений. Вот ключевые технологии, на которые стоит обратить внимание. Базовый манифест PWA с новыми опциями:{ "name": "MyApp", "short_name": "MA", "description": "Описание приложения", "start_url": "/", "display": "standalone", "background_color": "#ffffff", "theme_color": "#2196f3", "icons": [ {

В нескольких проектах пришлось серьезно оптимизировать под Core Web Vitals. Делюсь наработками по улучшению ключевых метрик. LCP (Largest Contentful Paint) — время загрузки крупнейшего контентного элемента:// Измерение LCP в коде new PerformanceObserver((entryList) => { for (const entry of entryList.getEntries()) { console.log(`LCP: ${entry.startTime}ms`); console.log(`LCP элемент:`, entry.element); } }).

Решение задачи: Основная проблема в коде — неправильное использование setState с объектами. При использовании useState с объектами React не делает автоматический мерж объекта, как в классовых компонентах с this.setState(). Вот что происходит:// Здесь мы заменяем всё состояние объектом { selectedUser } // А поля users и isLoading пропадают setState({ selectedUser }); Это приводит к тому, что после выбора пользоват

Недавно столкнулся с неочевидной проблемой в TypeScript. Найдите ошибку:interface User { id: number; name: string; email: string; } interface UserState { users: User[]; selectedUser: User | null; isLoading: boolean; } function UserList() { // Инициализация состояния const [state, setState] = useState<UserState>({ users: [], selectedUser: null, isLoading: false }); // Обработчик выбора

За последние годы перешел к более функциональному стилю кодирования и заметил, как это улучшило читаемость и надежность кода. Делюсь основными техниками. Вот пример в функциональном стиле:// Чистые функции без побочных эффектов const calculateTotal = (items) => items.reduce((sum, item) => sum + item.price * item.quantity, 0); // Композиция функций const compose = (...fns) => x => fns.reduceRight((acc, fn) => fn(

Последнее время работаю над оптимизацией загрузки изображений на сайтах. Два ключевых решения, которые реально улучшили и производительность, и визуал — это CSS-свойство aspect-ratio и HTML-атрибут srcset. Вот базовая реализация адаптивного изображения:<picture> <source media="(max-width: 480px)" srcset="image-small.jpg 480w, image-small-2x.jpg 960w" sizes="100vw" /> <source media="(max-width:

Решение задачи: В коде есть две основные проблемы: — Отсутствие обработчика onDragEnter или постоянного обновления dragOverItem: — При быстром перетаскивании можно "проскочить" через элементы, и onDragOver не сработает для всех элементов, над которыми проходит курсор. — Это может привести к некорректному определению целевой позиции. — Обработчик handleDrop привязан к элементам списка, но не к контейнеру: — Если поль

Showing the 12 most recent of 20 posts we hold for @frontendino. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.

Mentions

Names

Channels on the register whose handles appear in this channel's posts.

A mention is a weaker signal than a forward and is counted separately for that reason — naming a channel is not republishing it, and a handle in a post body is easy to place deliberately. The post counts beside each row below are distinct posts in which the handle appeared, from posts we have read on both sides — the “Named by N registered channels” figure above is a different count, of distinct NAMING CHANNELS rather than posts, and is not the sum of the rows under it.
