 What will be the output of this code. Explain your answer in 50 words or less.
+
+Ans: The output will be 9 and {x: 10}; This is due to the difference by which each of the 
+variables are passed. The variable x in f1 is passed by value, so the function will not modify the actual value of the variable.
+While in f2, the variable y is passed by reference, there manipulating the code in the function will result into modification of the value
+of the variable y.
