Piped buffer disappears when program terminates; is this a known bug?

I have described the issue in the following Stack Overflow question, https://ift.tt/2G8ayGv short, if you execute:node --eval "let index = 0; let output = ''; while (index < 1000000) { output += ' ' + (index++); } console.log(output); throw new Error('test');" | cat The program's last output is 12773 when the expected output is 999999.Execute it without pipe and you will get the full output.Where does the buffer disappear?
