模板字面量

在ES6之前,将字符串连接到一起的方法是+或者concat()方法,如

const student = {
  name: 'Richard Kalehoff',
  guardian: 'Mr. Kalehoff' }; const teacher = { name: 'Mrs. Wilson', room: 'N231' } let message = student.name + ' please see ' + teacher.name + ' in ' + teacher.room + ' to pick up your report card.'; 

模板字面量本质上是包含嵌入式表达式的字符串字面量.
模板字面量用倒引号 ( `` )(而不是单引号 ( '' ) 或双引号( "" ))表示,可以包含用 ${expression} 表示的占位符

let message = `${student.name} please see ${teacher.name} in ${teacher.room} to pick up your report card.`;
