Briefly explain why the head function is not considered “safe” in Haskell functional programming language.
Answer)
The functional programming language has a different way to work and contains the functions associated with it.
It has an operator which is the : that simply has the elements in the list and the pattern maching against the list with the head x and the tail xs are the list which has at least one element. The pattern matching can be done even when head is not executed. And as the function which is defined has resemblance with the informal description of the function hence it has semantic gap than any other languages and hence the head function are considered as not safe in Haskell function programming.

Haskell Functional Programming Language: Write a function nestedParens that takes a string argument and returns true if it is a nesting of zero or more pairs of parentheses, e.g. "((()))" should return True ; "()()" or "(()))" should return False . Use recursion for this problem. nestedParens :: String -> Bool
Please write below functions in HASKELL functional programming language and remember to include both the (1) function declaration, and (2) function definition. 1. Write a function sumLastPart which, only using library functions, returns the sum of the last n numbers in the list, where n is the first argument to the function. sumLastPart :: Int -> [Int] -> Int
Please briefly explain, alongside example code, how pattern matching on parameters in function definitions is actually just syntactic sugar for case expressions in Haskell functional language.

In Haskell programming language (1) Write a "averageThree" function to return the average of three integers. averageThree :: Integer -> Integer -> Integer -> Float (2) Write a "howManyAboveAverage" function which returns how many of three integer inputs are above its average value. (utilize the averageThree function.) howManyAboveAverage :: Integer -> Integer -> Integer -> Integer (3) Write a "howManyWithinThreshold" function that returns how many of the first three arguments are within the threshold (the fourth argument) of the average...

Javascript is a Functional programming language? (Select just one option) ( ) TRUE- it is the only functional language ( ) FALSE - Functional in Javascript refers to a different use of functions ( ) FALSE - but we can still write functional style programs ( ) TRUE - it can be translated to pure Lambda Calculus
Describe when and why you should use PHP (as a server-side programming language). Why a client-side programming language (like JavaScript), not enough? Also, is it generally safe to keep credentials like the Database passwords in PHP source code? Why? Compare that to doing the same thing in JavaScript.
