why console.log get different results if pass different parameters?

demo.js:

let obj = { foo: "bar\"bar" }
console.log(JSON.stringify(obj))        // it will get: {"foo":"bar\"bar"}
console.log(999, JSON.stringify(obj))   // it will get: 999 '{"foo":"bar\\"bar"}'

and then run:

node demo.js

why the two lines get different results?

The answer can be found if you look at this documentation. All the arguments are passed to util.format(), which returns a concatenation of all the given arguments if the first argument is not a string.

It first converts each argument to a string representation using util.inspect() before concatenating them. This explains why both lines return different results.
