To make it easier to review, here is a summary of changes. I am writing it down but I will update this comment with the final state.

1. The "add render script results" commit (46dd37e) only contains changes that happen after rendering.
2. Markdown lists are surrounded with empty lines.
3. Markdown headings get an empty line before the heading
4. Single quotes are turned into double quotes
5. ** is used instead of __ for bold emphasis in markdown
6. _ is used instead of * for italic emphasis in markdown
7. - for markdown listing instead of *
8. [{ constructs are split into two lines
9. Space between : and { in JSON, e.g. "fade": { instead of "fade":{
10. Lines longer than 120 characters are split into multiple lines. Similarly, if a line can be shorter than 120 lines, it is merged into one.
11. Unnecessary empty lines are deleted
12. JavaScript arrow function variable always has parantheses, e.g. filter((p) => p) instead of filter(p => p)
13. Semicolon ending is enforced
14. Enforcing 2 spacing for tabulation
15. Respecting indentation with each encapsulation

Notes:

• Even though this is a big diff, it should reduce diff size in the future.
• It is not possible to split this PR since the formatting has to apply everywhere.
• As this is just beautification, no change should happen that affects a visible or noticable result. Indeed, index.html almost doesn't change in the linked rendered diff above.
• I have reviewed the changed files but others are welcome.

In the TD call, we noticed the following changes:

1. We should add gitattribute file so that the first clone is using the correct line ending.
2. Having trailing comma in code without inline JSON would be better. So we can add prettierconfig in folders with just "normal" code or use // prettier-ignore inline. This avoids unintended diffs. This will be another follow up discussion.

@egekorkan will do the first point asynchronously and then merge the PR.

@relu91 I have added the gitattributes file as well. I have taken the one from node-wot but added some other file endings listed below:

• .puml
• .sparql
• .html
• .ttl
• .yml

I am merging the PR now. If there are other files I have missed, please provide a follow-up PR :)
