How are browserslist queries combined in a multi-line browserslist configuration?

Question

Browserslist documentation gives this example config:

{
  "browserslist": [
    "last 1 version",
    "> 1%",
    "maintained node versions",
    "not dead"
  ]
}

How are these lines combined into a single query? Query composition names three operators: or, and, and not, but the documentation does not say which, if any, is used to combine the queries in a config. How are these queries interpreted? I want to know the matching browsers.

Answer 1

End of line is used as union combiner

parse config content

Answer 2

This is my understanding of why it's the Union type from the docs
