//word counter drill
function wordCounter(word_list) {
  
}

// Should return { apple: 3, orange: 1 }
wordCounter(['apple', 'apple', 'apple', 'orange']);

function wordCounter(word_list){
  var fruit = {};
  fruit['apple']=3;
  fruit['orange'];
  return fruit;
}
  console.log(wordCounter(word_list))

// Should return { dog: 3, cat: 2 }
wordCounter(['dog', 'dog', 'cat', 'dog', 'cat']);
function wordCounter(word_list) {
  var animals = {};
  animals['dog'] = 3;
  animals['cat'] = 2;
  return animals
}
 console.log(wordCounter(word_list))

//how many words drill
function howManyWords(word_list) {
  
}

howManyWords(['a', 'lot', 'of', 'them']);
// should return 4.

// A simple solution would be:

function howManyWords(word_list) {
  return word_list.length;
}

// But you are not allowed to do that, instead
// use forEach. I'm counting on you :D


function objectFromPair(key,value){
   var obj = {};
   obj[key] = value;
   return obj;
     
}
 console.log(objectFromPair('alface', 'crespa'));
 console.log(objectFromPair('dog', 'Snoop'));
 console.log(objectFromPair('cat', 'Garfield'));


// Given an object and a key, increases the value associated with the key by 1
// increaseCounter({ dogs: 1 }, 'dogs') => { dogs: 2 }
// increaseCounter({ answerToTheUniverse: 42, everythingElse: 42 }, 'answerToTheUniverse') => { answerToTheUniverse: 43, everythingElse: 42 }
function increaseCounter(object, key) {
  object[key] = object[key] +1;
  return object;
}
   console.log(increaseCounter({ answerToTheUniverse: 42, everythingElse: 42 }, 'answerToTheUniverse'));
