Question

I wrote this code on my website

for(var i = 0; i < 10; i++){
    console.log([] > []);
}

and got this output

LOG: false 
LOG: true 
LOG: true 
LOG: false 
LOG: false 
LOG: false 
LOG: true 
LOG: false 
LOG: true 
LOG: false 

The output changes every time I run it. Why is this strange behavior happening?

You can try it out for yourself on this jsFiddle demo.

Answer 1

In the jsFiddle, Array.prototype.toString has been overridden with the following…

function () {
    return Math.random();
}

Try it like this…

[].toString(); // 0.6317324512006824
