Why it is undefined

#1

var foo = { bar: function() { return this.baz; }, baz: 1 }; (function(){ return typeof arguments[0]; })(foo.bar);

here typeof is function

var foo = { bar: function() { return this.baz; }, baz: 1 }; (function(){ return typeof arguments0; })(foo.bar);

then when function is called why type of is undefined

#2

In both cases I am getting value of foo and can’t find what exactly you are trying to say is undefined, can you write a console.log() to show what you are trying to say is undefined
