Description
I was reading chapter 6.3 Variable scope, closure and I came across the Lexical Environment part. I tried to find it in the latest EcmaScript specification and I found only section about Environment Record. There is a difference in the Environment Record structure.
Every Environment Record has an [[OuterEnv]] field, which is either null or a reference to an outer Environment Record.
Lexical Environment was removed in this PR: https://github.com/tc39/ecma262/pull/1697.

Research direction
Start with chapter 6.3, specifically the Lexical Environment section, and compare its explanation with the current ECMAScript Environment Records section and the linked TC39 PR. Update the outdated terminology and structure description so it matches the current specification, preserving the tutorial’s explanation and links.
