7 posts held, back to 24 January 2020 — the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 1 pageof 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 7 posts for this entry, the most recent from 13 May 2022. An engagement rate over an empty window would be a number about nothing.
64 reactions across 3 posts, in 4 distinct kinds. The most used accounts for 48.4% of them.
| Reaction | Count | Share | Share, drawn |
|---|---|---|---|
| 🔥 | 31 | 48.4% | |
| 👍 | 29 | 45.3% | |
| 👎 | 3 | 4.69% | |

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 4 of the 7 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 64reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 7 most recent posts we hold, published 24 January 2020 to 13 May 2022, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

Дополнительная информация: - Google в своем стайлгайде предлагает использовать именованные экспорты: https://google.github.io/styleguide/jsguide.html#es-module-exports - В Gitlab перешли на именованные экспорты: https://gitlab.com/gitlab-org/frontend/rfcs/issues/20
Исключения: - Экспорт основного содержимого библиотеки. (например, чтобы можно было сделать так: import React from 'react') Тем не менее, обычно это все еще нежелательно. - Некоторые модули, которые в соответствии с архитектурой фреймворка должны быть экспортированы по умолчанию. (например, компоненты страниц в Next.js) - Различные конфиги и все остальное, чьими потребителями является программный код, а не р…
- export default позволяет экспортировать анонимные функции: Если где-либо будет выброшена ошибка, в ее stack trace все анонимные функции, через которые она прошла, будут помечены записью at <anonymous>, что усложнит поиск места возникновения данной ошибки. В React, если таким способом экспортировать компонент, он не получит имени в дереве компонентов в React DevTools, следовательно будет сложнее увидеть полную кар…

Showing the 7 most recent of 7 posts we hold for @why_not_export_default. 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.
A live page changes as we take new readings, so a citation should name the measurement it is based on, not just the URL. The line below cites the subscriber count as measured 20 August 2026 — this entry's latest reading, not the date you are reading this.
