ESX (e.g. ES5, ES6, ES10) refers to versions of JS. Every new version adds some new features. If you find a tutorial that teaches ES6, it'll still be broadly applicable to ES10, it might just turn out that there are better ways to do one or two of the things you learn. That being said, learning the "old way" will still make it much easier to learn the "new way." Answer from PPewt on reddit.com

u/PPewt ‘s explanation is spot on. People often reference ES6 because of the big updates it brought to the Ecmascript standard. ES6 brought changes to the JavaScript syntax like ‘let’ and ‘const’ for variable declaration, class syntax, and “fat arrow” function declaration. These (and other) updates shifted how people write JavaScript, making ES6 pivotal in its way. You should take time to learn how to read and write the JavaScript syntax in its older and newer forms. Learn the difference between ‘var’ and ‘let’, the ‘function’ keyword and ‘=>’, etc. It’s tricky, but it’ll make you a stronger developer and team member.

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.
