Which Javascript Version is currently the most used?
ES6+ ES6 was a game-changer. All the others after that add little things, but we don't really talk about them as being special versions like ES6. They're just extra features. Basically, if you come across tutorials or lessons using var, steer clear. It's really old. Anything using let and const is at least reasonably up-to-date. More on reddit.com

May 11, 2021There are 12 ECMASCRIPT versions, yet people mention only ES5, ES6 or ES7. Why?
ES6 fundamentally changed the JS world; Arrow functions, template literals (+multi-line strings), let/const, default function parameters. Making the language finally usable for more than your little 200 lines script. These were such important features (especially arrow functions) that it got quite a big hype. It was seens as the "HTML5"-package which included ES6 & CSS3. During that time a new era of the web has sparked, where folks were more seriously building SPAs with React, Vue & Angular. Before that you were usually using jQuery or maybe some AngularJS here and there. Usually things were server-side rendered (with e.g. PHP, C#, Java) and then some dynamic functionality was glued on web applications using jQuery. JS was kind off an after-thought. The versions after were quite important as well off course, but never to the same degree. The one feature which was similar scale in my opinion is async/await.

The answer is "the current version". Today's modern browsers are all updated regularly and do very well with supporting the latest version of JavaScript (ECMAScript). So when it comes to user support, it will be very good for whatever the current version is. In fact, one of the criteria for adding new features to the language is that there are implementations of that feature already in existence. So often browsers like Chrome will have new features available and working before they're even officially features of the language. Despite that, modern development makes use of tools like Babel and TypeScript which allow developers to write modern code (current version code) while still being able to deploy older version code in order to support any users that don't have the most up to date browsers. This means developers don't have to worry as much about what versions users can support. Instead they write code in the current version of the language and it will automatically work everywhere for everyone (within reason) thanks to some build magic. On top of all that, given that you're still just learning, consider the fact that as time goes by, anything you're learning that's new now might not be so new once you put it into practice for real. Technology moves quick. Don't be left behind by focusing on what's most compatible now since that may soon be obsolete.

The Evolution of JavaScript: A Journey from ES1 to the Latest Version (Part 1)
October 29, 2023 - Functions: Functions were at the core of JavaScript's design from the beginning, allowing developers to encapsulate and reuse code. Objects: ES1 included support for creating and manipulating objects, which played a crucial role in defining the language's object-oriented nature. ES2 was a minor update that focused on improving the existing features and clarifying the language's specification. No major new features were introduced in this version.

Out of all the JS versions,ES6 is the mostly mentioned one in google trends. Which is odd because ES5 seemed to be the standard for 6 years before ECMA2015. And ES7 added async / await which is pretty big. Everything after ES7 is almost unheard of.
Is there a reason why ES6 is such a big deal as opposed to ES7 or ES10?

It's kind of how people talk about "Angular 2" when they mean Angular 13 or whatever the latest version is. ES6 was the first version that departed from "old" javascript, and required a transpiler to work on most browsers. At the time you either used "old javascript", or ES6 with babel, so "ES6" basically became a synonym for "modern javascript" and it stuck even though ES6 is technically pretty outdated now.

JavaScript was invented by Brendan Eich in 1995, and became an ECMA standard in 1997. ECMAScript is the official name of the language. ECMAScript versions have been abbreviated to ES1, ES2, ES3, ES5, and ES6.

JavaScript Versions: ES6 and Before | Codecademy
To fully distinguish the difference between JavaScript and ECMAScript: if you want to create an app or program you can use JavaScript — if you want to create a new scripting language you can follow the guidelines in ECMAScript. So, when you see ES6 or JavaScript ES6, it means that that version of JavaScript is following the specifications in the sixth edition of ECMAScript!

According to Wikipedia, the JavaScript-specific version numbers were only used by Firefox, and were dropped in Firefox 4.
These days, there's not really such thing as 'the current version of JavaScript' - the ECMAScript standards get created, and the browser vendors implement the features into their JS engines at their own pace. This pace varies wildly - as demonstrated by the very useful Kangax compatibility table.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/New_in_JavaScript#JavaScript_versions:
Deprecated. The explicit versioning and opt-in of language features was Mozilla-specific and is in process of being removed. Firefox 4 was the last version which referred to an JavaScript version (1.8.5). With new ECMA standards, JavaScript language features are now often mentioned with their initial definition in ECMA-262 Editions such as ECMAScript 2015.
Starting with Firefox 5, changes in JavaScript are listed at https://developer.mozilla.org/en-US/docs/Web/JavaScript/New_in_JavaScript/Firefox_JavaScript_changelog, but not versioned otherwise.
See the lists at ECMAScript 2015 support in Mozilla and ECMAScript Next support in Mozilla for which features are available in which version of Firefox.

May 22, 2026 - The standards for JavaScript are the ECMAScript Language Specification (ECMA-262) and the ECMAScript Internationalization API specification (ECMA-402). As soon as one browser implements a feature, we try to document it. This means that cases where some proposals for new ECMAScript features have already been implemented in browsers, documentation and examples in MDN articles may use some of those new features.
