初步使用ES6，最让我混淆的就是，同样是console.log( )用法是什么时候该用单引号，双引号或是斜杆``呢？
于是提交到前端学习分享群，不到几分钟便有热心的前端人员详细回答，还有推荐书籍。真是感激不尽，平时大家不闲聊，有问题马上出手帮忙，氛围真是太好了。
解答
单引号和双引号一样也是普通字符 斜杠是模版字符，斜杠是es6新出的语法，为了解决"字符串"+"字符串"这种问题。

// Enter your name
const userName = "Alex";
userName ? console.log( Hello, ${userName} ):
console.log('Hello');
const userQuestion = 'Can you answer my question?';
console.log( The user aksed: ${userQuestion} );
let randomNumber = Math.floor(Math.random() *8);
let eightBall = ' ';
switch(randomNumber){
case 0:
eightBall = 'It is certain';
break;
case 1:
eightBall = 'It is decidedly so';
break;
case 2:
eightBall = 'Reply hazy try again';
break;
case 3:
eightBall = 'Cannot predict now';
break;
case 4:
eightBall = 'Do not count on it';
break;
case 5:
eightBall = 'My sources say no';
break;
case 6:
eightBall = 'Outlook not so good';
break;
case 7:
eightBall = 'Signs point to yes';
break;
}
console.log(eightBall);
