利用ES6中的模板字符串轻松实现多行和字符串值的插入

多行字符串

// Multiline strings
`In JavaScript template strings can run
 over multiple lines, but double and single
 quoted strings cannot.`
// 如打印或者输出，是多行的结构

字符串值的插入

// String interpolation
var name = 'Bob', time = 'today';
`Hello ${name}, how are you ${time}?`
// console:   "Hello Bob, how are you today?"
