JS versiyalari
JavaScript’ning joriy versiyasi
Joriy JavaScript versiyasi — ES2025.
ECMAScript JavaScript standartining rasmiy nomidir.
JavaScript 1995 yilda Brendan Eich tomonidan ixtiro qilingan va 1997 yilda ECMA standartiga aylandi.
Dastlabki ECMAScript versiyalari raqamlar bilan qisqartirilgan (ES1, ES2, ES3, ES5, ES6).
2016-yildan boshlab versiyalar yil bo‘yicha nomlanadi (ECMAScript 2016, 2017, 2018, ..., 2025).
W3Schools barcha JavaScript versiyalarini qamrab oladi!
