Intellisense support for js protocol

[Mzack9999]

Please describe your feature request:

Writing templates in js protocol should be intuitive and avoid continuous back and forth between docs and template editor, requiring multiple trials before grasping how the libraries and logic works. In order to improve the template writers experience it would be helpful either:

• Add a language server, or somehow enable intellisense for js
• Since ECMA js can run in the browser as well, mock various libraries call and execute the js snippet in the browser within the template editor at https://templates.nuclei.sh, the final effect should be something like this, allowing users to intuitively and incrementally build code.
