ES7 is a smaller update compared to ES6, and it doesn't introduce as many new features. Some key additions include:

Exponentiation Operator: The exponentiation operator (**) was introduced for easier calculation of exponentials. Array.prototype.includes: The includes method was added to arrays for a simpler way to check if an array includes a certain element.

Major ECMAScript versions like ES6 and ES7 aim to enhance and extend the language rather than deprecate existing features.

r/webdev on Reddit: There are 12 ECMASCRIPT versions, yet people mention only ES5, ES6 or ES7. Why?
May 31, 2022 -

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?

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.
