Consider the following code snippet
function hypotenuse(a, b)
{
function square(x)
{
return x*x;
}
return Math.sqrt(square(a) + square(b));
}
What does the above code result?
function hypotenuse(a, b)
{
function square(x)
{
return x*x;
}
return Math.sqrt(square(a) + square(b));
}
A. Sum of square of a and b
B. Square of sum of a and b
C. Sum of a and b square
D. None of the mentioned
Answer: Option A
Solution (By Examveda Team)
The above code snippet contains nested function in which the function hypotenuse(a,b) has another function inside its scope, function square(x). The interesting thing about nested functions is their variable scoping rules. They can acceess the parameters and variables of the function (or functions) they are nested within.This Question Belongs to Javascript >> Array And Function
