What “ecmascript” means

Wikipedia

ECMAScript is the standard for the JavaScript language, intended to ensure the interoperability of web pages across different web browsers. It is standardized by Ecma International's TC39 technical committee in the document ECMA-262, with i18n ("Intl") APIs standardized in the document ECMA-402.

#ecmascript across platforms

every network with a public tag surface

Follow #ecmascript straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.

X (Twitter) ↗Instagram ↗TikTok ↗Facebook ↗LinkedIn ↗YouTube ↗Threads ↗Bluesky ↗Mastodon ↗Reddit ↗Pinterest ↗Tumblr ↗

Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/ecmascript
