10 measurements spanning 22 days, net +1,963. 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 4,789–7,604 and does not start at zero.

ERR is average views per post over the last 30 days divided by subscribers, the definition TGStat uses, so this figure is comparable with the one you will see elsewhere. It falls structurally as a channel grows: a high ERR on a small channel and a low one on a large channel describe reach mathematics, not quality. We publish the figure and the sample it came from and pass no verdict on it.

ER is defined industry-wide as (forwards + reactions + comments) ÷ views — note the denominator is views, not subscribers. Telegram’s public web preview carries views and reactions but not forward or comment counts, so the reaction rate above is the reactions term only and is therefore a floor: the true ER for this channel is higher by an amount we have not measured and will not estimate. It is computed over the 48 of 55 measured posts that carry a reaction reading, and over those same posts' views.

Readings taken12 Aug 2026, 04:46 UTC

Views are a single reading per post, taken at the time above. A post published in the last day or two is still accumulating views, which pulls the 30-day average down slightly. That is a property of the standard definition rather than a fault in it, so we keep the definition rather than “correcting” the number into something nobody can reproduce.

Precision. Telegram publishes view counts on its public widget in short form — 8.12K, 3.7M — so any reading at or above 1,000 reaches us rounded to three significant figures, and only counts below 1,000 are exact. Averages and rates derived from them are shown to the same precision rather than to the unit: a figure like 3,701,250 would assert digits nobody measured.

Reaction counts are published per emoji and rounded the same way, so a total below 1,000 is exact and a larger one is a sum that may carry a rounded component from each emoji above 1,000. Because it is a sum, it does not look rounded — read a large reaction total as three significant figures per contributing emoji rather than as the figure it prints.

Reaction mix

184 reactions across 47 posts, in 7 distinct kinds. The most used accounts for 66.3% of them.

Every reaction kind recorded on the sample, most used first

👍137.07%
❤‍🔥84.35%
👏84.35%

💯31.63%

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 48 of the 56 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 184 reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.

Measured over the 56 most recent posts we hold, published 5 August 2026 to 11 August 2026, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

🤔 Hoisting در JavaScript چیه؟ قبل از اجرای کد، بعضی Declarationها در فرآیند ایجاد Execution Context پردازش میشن. برای همینه که این کد: sayHi(); function sayHi() { console.log("Hi"); } کار می‌کنه. ✅ ولی رفتار let و const با var فرق داره. 📌 Hoisting رو با «انتقال واقعی کد به بالا» اشتباه نگیر.

🚨 اگه Front-End کار می‌کنی، این اشتباه CORS رو باید بشناسی! وقتی Front-End و Backend روی Originهای متفاوت باشن، مرورگر ممکنه درخواست رو بلاک کنه. مثلاً: frontend.com → api.com و یهو می‌بینی: ❌ CORS Error نکته مهم: CORS معمولاً مشکل Backend/Server Configuration هست، نه اینکه JavaScript تو خراب باشه! ؛ این خطا دیر یا زود سراغت میاد.

بیا یه واقعیت بازار کار رو با هم ببینیم. 👇 این آگهی‌های Front-End، حقوق ۶۰ تا ۷۰ میلیون گذاشتن رو باز کن ببین. حتی آگهی‌پایین تری ۶۰ تا ۱۰۰ میلیون حقوق در نظر گرفتن. برای کسی که به: JavaScript + React + Next.js + TypeScript مسلط باشه، حالا یه سؤال: چرا این شرکت‌ها اکانت ChatGPT نمی‌خرن و نمی‌گن خودش برامون سایت یا ابزار بسازه؟ 😂 چون مسئله شرکت فقط نوشتن کد نیست. وقتی پروژه بزرگ میشه، باید بتونی: 🔹 معماری درست ط

🌐 SSR یا CSR؟ کدوم بهتره؟ CSR → صفحه بیشتر سمت Browser ساخته میشه. SSR → HTML صفحه روی Server تولید میشه و بعد به کاربر می‌رسه. 🚀 CSR → مناسب اپلیکیشن‌های تعاملی 🔍 SSR → مناسب صفحاتی که SEO و نمایش سریع محتوا مهمه ❌ هیچ‌کدوم همیشه بهتر نیست. انتخاب درست، به نوع پروژه بستگی داره.

Showing the 12 most recent of 56 posts we hold for @codelines_ir. 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.

Percentages only — there are no per-option vote counts here, because Telegram publishes none. The public post preview gives each option’s share and a single voter total, and nothing else. Multiplying one by the other would produce a per-option tally that looks measured and is not: the shares are rounded to whole numbers before we ever see them. We print what was published and leave the column that does not exist empty.

The shares need not add up to 100. Rounding alone puts many polls at 99 or 101. A poll that allows more than one answer per voter runs well past 100 by design, and several here do. The bars are drawn against a fixed 100% track at each option’s own percentage rather than normalised to the total, so a poll that exceeds it shows that it does instead of being quietly rescaled.

Read from the 56 most recent posts we hold, published 5 August 2026 to 11 August 2026. Telegram labels each poll by kind — an anonymous poll, a quiz, a closed set of final results — and that label is reproduced rather than paraphrased.

Citation-graph rank

Citation-graph rank — 477,437 of 1,629,452 entries in the measured graph. A weighted position computed from the forward and mention edges below — republished posts weigh more than named mentions — and recomputed periodically, over the whole graph. Published only as this ordinal position, never as a score: a position is a fact, and a score printed beside one channel’s name would read as a verdict this register does not make. The two counts beneath stay separate for the same reason mentions are never summed with forwards anywhere else on this page — a named-by count costs nothing to manufacture. The top 100 by this measure, or how it is computed.

Forward network

Republished by

Channels on the register that have forwarded this channel's posts into their own feed.

Built only from forwarded posts we have actually read, on both sides. Coverage is early and deliberately incomplete: a missing link means we have not read the post that would prove it, never that the relationship does not exist. Counts are distinct forwarded posts observed, so they only ever go up as we read more.
