// Write a function, returnFive, that returns the number five. No inputs should be defined.

//function returnFive() {
//    return 5;
//}
//    console.log(returnFive());

// Write a function, isFive, that takes in an input and returns the boolean value true if the passed argument is the number 5 or the string "5". Return false otherwise.
  //how many inputs should the function have? 1
  //what are the data types for the inputs? number, string, any data type
  //what is the data type of the output/return value boolean

//  function isFive(input) {
//      return input == 5;
//  }

//  console.log(isFive('5'), true);
//  console.log(isFive(5), true);
//  console.log(isFive('zzz'), false);
//  console.log(isFive(33), false);

// Write a function, isShortWord, that takes in a string and returns the boolean value true if the passed argument is shorter than 5 characters. Return false otherwise.
//how many inputs? 1
// what data type for inputs? string
// what is the return type?  boolean

  function isShortWord(stringInput) {
      return stringInput.length <5;

  console.log(isShortWord('aaaaa'), false);

// Write a function, isSameLength, that takes in two string inputs and returns the boolean value true if the passed arguments are the same length. Return false otherwise.

  function isSameLength (str1, str2) {
      // create variable to store boolean comparing strings
      var stringsAreSameLength = str1.length === str2.length
      //return variable outout

  }
// example of inputs and outputs
  console.log(isSameLength('cat', 'hat'), true);
  console.log(isSameLength('dog', 'plane'), false);
  console.log(isSameLength('  ', 'dog'), true);


// Write a function, getSmallerSegment, that takes in a string and a number input. The function should return a substring of the first argument that is as many characters long as the second argument in lowercase.

// example input: getSmallerSegment("Codeup", 3)
// example output: "cod"
  // how many inputs? 2
  // what types of inputs? string, number
  // what type of output? string

  function getSmallerSegment(str, segmentLength) {

  console.log(getSmallerSegment('dog', 1), 'd');
  console.log(getSmallerSegment('Hello', 2) 'he');
  console.log(getSmallerSegment('seventeen' 5), 'seven');
