Psst: Open the JavaScript Console and try to play around with these functions:

• reverse('awesome') // should return 'emosewa'
• isPalindrome('tacocat') // should return true
• someRecursive([4,6,8,9], val => val % 2 !== 0) // should return true
• everyRecursive([4,6,8], val => val % 2 === 0) // should return true
• flatten([1, [2, [3, 4], [[5]]]]) // should return [1, 2, 3, 4, 5]
• capitalizeFirst(['car','taco','banana']); // should return ['Car','Taco','Banana']

•           
  let obj1 = {
    a: 2,
    b: {b: 2, bb: {b: 3, bb: {b: 2}}},
    c: {c: {c: 2}, cc: 'ball', ccc: 5},
    d: 1,
    e: {e: {e: 2}, ee: 'car'}
  };
  
  nestedEvenSum(obj1); // should return 10
            
          

• capitalizeWords(['i', 'am', 'learning', 'recursion']); // should return ['I', 'AM', 'LEARNING', 'RECURSION']

•           
  let obj2 = {
    num: 1,
    test: [],
    data: {
      val: 4,
      info: {
        isRight: true,
        random: 66
      }
    }
  };
  
  stringifyNumbers(obj2);
  
  // should return the ff. object:
  /*
