I have this snippet of code

function foo() {
    console.log(this.bar);
}

var bar = "bar1";
var o2 = { bar: "bar2", foo: foo };
var o3 = { bar: "bar3", foo: foo };

foo();          // "bar1"
o2.foo();       // "bar2"
o3.foo();       // "bar3"

when run in browser it shows the output

bar1
bar2
bar3

but when run it with node it outputs

undefined
bar2
bar3

Can someone explain why am I getting different outputs?

Tried your example, the output is the same. Which node version do you use? – Eugene Olisevich Feb 09 '18 at 09:35

@EugeneOlisevich I think OP is running it as a node script, not in the REPL – Bergi Feb 09 '18 at 09:39
I test ran as OP described, in a browser and on nodejs. The OP's results seem valid. – ViKiG Feb 09 '18 at 09:46
@EugeneOlisevich I am using node v7.5.0 – Syed Shamikh Shabbir Feb 09 '18 at 10:39
