[Feature] Consider/ Requesting Access to read-only AST of Javascript Parser

[ganeshkbhat]

What is the problem this feature will solve?

Has the Access AST of the javascript module proposal been accepted into tc9 and node.js? Can someone take lead and help raise an proposal for this?

Can you make the AST available as read-only to developers in browsers [rethink security concerns] and js server environments if not on browers? Seems like the mozilla docs Parser_API documentation is somehow removed and I am still wondering how to access the file's parsed, even if read-only, AST

1. Access AST: Proposal status: Access AST of the javascript module nodejs/node#45158
2. Use Cases of AST like JS Parsers: access the import cache imported packages cache like require.cache nodejs/node#45207
3. https://stackoverflow.com/questions/16127985/what-is-javascript-ast-how-to-play-with-it

I wish to strongly vote for it, if this is in consideration. I recommend the access using a separate nodejs module api, if requested for my view. pls consider security and runtime risks based on your immense experience with such an nodejs module api access without a commandline's force access ast option enabled or other secure alternatives.

What is the feature you are proposing to solve the problem?

Access AST of the javascript module in runtime engines if not on browsers.

What alternatives have you considered?

1. Using a bundler parser like ESTree, Typescript, and Babel. https://stackoverflow.com/questions/16127985/what-is-javascript-ast-how-to-play-with-it
2. Use Cases of AST like JS Parsers: access the import cache imported packages cache like require.cache nodejs/node#45207
3. One of many JS Parsers [Use Cases]: Upgrade to latest version of ECMAScript 2021/ 2022 dop251/goja#498
4. JS Parsers in the market [Use Cases]: https://github.com/fkling/astexplorer

@bnoordhuis adding to this, it seems like/ behaviour none of the variable's, let's, const's, function's declaration made in the code already without using declarations like global.variable is not accessible from globals even as read-only which should not be the case. A presence of this or access to #717 or nodejs/node#45158 can lead to better AST or (read-only) access to variables.

I am seeing acorn: 8.10.0 here. What is this and what is the relevance here? Any way to access this in the newer versions of nodejs?
