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.`;
