Current and expected behavior

When parsing and re-printing (with no transforms) Babel generates this code:

a * b // c
satisfies c;

It should instead wrap the LHS in parens, and generate

(
  a * b // c
) satisfies c;

Environment

• Babel 7.25.3

Possible solution

No response

Additional context

This is quite annoying to fix. We are currently checking if the expression contains any trailing comments, but we should instead check if any right-most descendants of the expression do.

Also, some cases already have parens due to operator precedence, so while fixing this issue we must make sure to avoid double parens, e.g.

(
  a || (b // c
)) satisfies c;
