You are a bit confused. The different ECMAScript specifications are implemented by browsers. It's not a finished product vendors just include and get all the new functionality. Those new features need to be implemented and tested. All the major browsers have 100% conformance to ES7 and are working on bits of later specs (Firefox for example supports everything in ES2020 and some in progress parts of ES2021). If you need something from later specs that isn't supported in a certain browser you might be able to use a polyfill. Answer from Northeastpaw on reddit.com

JavaScript ES11: What’s New? | 10 New Features of ES11 in 2020
July 20, 2020 - When you want multiple Promises to complete, you can use Promise.all ([promise_1, promise_2]). In this process, if one of the promises fails, the JavaScript engine will throw an error. Luckily, there are cases in which the failure of one promise doesn’t matter, and the rest would resolve. To achieve that, the new JavaScript ES11 unpacks Promise.allSettled.

r/learnprogramming on Reddit: Why is JavaScript using ES6 if ES11 is already out? Why is it that far behind?
August 4, 2020 -
I’m confused about why JS adopted ES6 as the most recent ECMAScript when ES11 is out.
My question is why is JS so far behind on these specifications and is there a reason they will continue to be that far behind?

The version numbers are a convenience but not really that important. As a developer what you care about is features and which browsers support them. For that, I doubt there's a better site than this: https://caniuse.com/ Though some of this browser support information is also at the bottom of the MDN docs.

Hey there.
You should check the Global Administration Marketplace tab of your SonarQube instance to see what version of the Javascript analyzer is installed on your SonarQube server. If it’s not the latest compatible with the v7.9 LTS (v6.2.2) you can also use the Marketplace to update it.

Hey there.
What version of SonarQube and its Javascript analyzer are you using? This should be addressed in the latest version available for v7.9 LTS (v6.2.2) and whatever version comes bundled in the latest version of SonarQube, v8.5
