// Question 1: Anonymous Function
// Write an anonymous function that takes two numbers as parameters and returns their sum.

var add = function (x, y) {
  return x + y
}

console.log(add(10, 5))

console.log("\n-------------------------------------------------\n");

// 2. Write a function `isEven` that takes a number as a parameter and returns `true` if it is even, and `false` otherwise.

function isEven (number) {
  var remainder = number % 2
  var even = remainder === 0
  return even
}

console.log(isEven(4))
console.log(isEven(11))


console.log("\n-------------------------------------------------\n");

// 3. Implement a function that checks if a given number is a palindrome (e.g., 121, 1331).

function isPalindrome (number) {
  console.log(number)
  const string = String(number)
  console.log(string)
  const array = string.split('')
  console.log(array)
  array.reverse()
  console.log(array)
  const joined = array.join('')
  console.log(joined)
  return string === joined
}

console.log(isPalindrome(123))
console.log(isPalindrome(54845))

console.log("\n-------------------------------------------------\n");

// 4. Scope - Global and Local
// Write a function that demonstrates the concept of global and local scope. The function should have a local variable and a global variable, and it should print their values.

var global = 'global'

function test () {
  var local = 'local'
  console.log(global)
  console.log(local)
}

test()

console.log("\n-------------------------------------------------\n");

// 5. Anonymous Function as a Parameter
// Write a function that takes an anonymous function as a parameter and invokes it.

function parent (child) {
  console.log('before')
  child()
  console.log('after')
}
parent(() => console.log('I am the child'))

console.log("\n-------------------------------------------------\n");
