Tests:

  • Switch

     
    var animal = ["dog", "cat", "cattle", "cheetah"][Math.floor(Math.random() * 4)]
    ​
    function test(animal) {
      switch(animal){
       case 'cat': return 'Kitten'
       case 'cattle': return 'Calf'
       case 'cheetah': return 'Cub'
       case 'dog': return 'Pup'
       default: return "I don't know that"
      }
    }
    ​
    console.log(test(animal))

  • Object Literal

     
    var animal = ["dog", "cat", "cattle", "cheetah"][Math.floor(Math.random() * 4)]
    ​
    function test(animal) {
      var babyAnimal = {
       cat:'Kitten',
       cattle:'Calf',
       cheetah:'Cub',
       dog:'Pup'
      }
    ​
      return babyAnimal[animal] ?? "I don't know that"
    }
    ​
    console.log(test(animal))

  • If Else

     
    var animal = ["dog", "cat", "cattle", "cheetah"][Math.floor(Math.random() * 4)]
    ​
    function test(animal) {
      if(animal==='cat'){
        return 'Kitten'
    } else if(animal=='cattle'){
         return 'Calf'
    } else if(animal==='cheetah'){

         return 'Pup';
    }
       return "I don't know that"
    }
    ​
    console.log(test(animal))

  • Object Literal defined outside function

     
    var animal = ["dog", "cat", "cattle", "cheetah"][Math.floor(Math.random() * 4)]
    ​
    function test(animal) {
    return babyAnimal2[animal] ?? "I don't know that"
    }
    ​
    console.log(test(animal))

  • Map

     
    var animal = ["dog", "cat", "cattle", "cheetah"][Math.floor(Math.random() * 4)]
    ​
    function test(animal) {
      const map1 = new Map();
    ​
      map1.set('cat', 'Kitten');
      map1.set('cattle', 'Calf');
      map1.set('cheetah', 'Cub');
      map1.set('dog', 'Pup');
    ​
      return map1.get(animal) || "I don't know that"
    }
    ​
    console.log(test(animal))

  • Map - defined outsid function

     
    var animal = ["dog", "cat", "cattle", "cheetah"][Math.floor(Math.random() * 4)]
    ​
    function test(animal) {
      return map2.get(animal) || "I don't know that"
    }
