equivalent of python's open('abc.txt').xreadlines in node.js

[junyi sun]

Hello, I am a newbie of Node.js, which is a great for javascript server-side programming.

I have a trial question, is there a way to read a file or stdin line by line, in a high performance way.

It should be like open('abc.txt').xreadlines in python and io.lines("abc.txt") in Lua.

Thanks.

require('fs').readFileSync('abc.txt').toString().split('\n').forEach(function (line) { line; })

But only for smallish files because this slurps the entire file into
memory. Node core doesn't have a readlines() or xreadlines()
equivalent, that's fairly high level.
