onst d = 4 let a = 1 if (true) { let a = 4 var b = 2 if (a < 5) { var c = 1 b = 5 } } console.log(a + b + c) What is is the output and why? a) The output is 7 because a, b, c and d are globally scoped variables b) The output is 11 because a, b, and c are all globally scoped variables while d is a block scoped variable c) The output is 7 because b and c are globally scoped variables d) The output is 6 because a is a block scoped variable and b is a globally scoped variabl

Types of Function

A function is a process or task that does some operation in the program. Some programming languages may contain built-in functions for certain commonly used tasks. Most programming languages also support user-defined functions, which means a user can write their own function to perform some operation. There are some libraries or header files that contain built-in functions for performing certain tasks.
