var str = 'abc';
str = str.charAt(Math.floor(Math.random() * 3));
Tests:

  • If - Else

     
    if(str === 'a'){
        console.log('A'); 
    } else if (str === 'b'){
        console.log('B'); 
    } else if (str === 'c'){
        console.log('C'); 
    }

  • Switch - Case

     
    switch (str) {
      case 'a': console.log('A'); break;
      case 'b': console.log('B'); break;
      case 'c': console.log('C'); break;
    }

  • Object literals

    ​x
     
    var objLiteral = {
      a: function() {
        console.log('A');
      },
      b: function() {
        console.log('B');
      },
      c: function() {
        console.log('C');
      }
    }
    ​
    objLiteral[str]();

  • ternary-operator

     
    str === 'a' ? console.log('A') : str === 'b' ? console.log('B') : str === 'c' ? console.log('C') : console.log('nothing')
