Tabs vs spaces?

Questions
1

I’d like to get an idea of the BJS communities’ stance on tabs vs spaces, which is a very common and sometimes passionate argument.

I think Babylon would benefit from using tab for a number of reasons:

  1. Accessibility: Tabs are easier to use for many individuals with physical or neurological disabilities.
  2. Size: Spaces take up 4 times as much space as a tab in Babylon’s case (4 bytes for spaces and 1 byte for tabs in UTF-8)
  3. Customizability: Developers working on or with Babylon can configure their editors to render tabs as 2, 4, 8, etc. spaces
  4. Tabs are easier to use for new developers. When using spaces, some will actually press space 2/4/8 times instead of using the tab key
  5. We use the tab key, not the space key to indent- doesn’t it make more sense for the tab key to insert a tab instead of spaces?

prettier/prettier#7475 has a significant amount of discussion I spent hours going through.

What do you all think?
