Hi @mansisingh2803,
The question states to predict the output of the following code

var foo = 'I am foo';
function test() { var foo = 'I am foodoo'; }
console.log(foo);

Here the output will be ‘I am foo’ and the reason for the same will be because the variable foo is Redefined as var foo = ‘I am foodoo’ . This wouldn’t have happened if only it would have been reassigned then the value of foo would have been I am foodoo but here it is redefined/redeclared and therefore the output doesn’t change as the program identifies the previous foo only .The newly defined foo will have the scope of the test function. To read and know more bout scope kindly visit the link.
