Template Literal | Kuroda Kayn's Blog

有时候我们会遇到要处理多个字符串+常量/变量的情况比如需要输出“My name is” 如果用字符串拼接的写法，那么写法就如下

const name = "Kayn";
console.log("My name is" + name);

这样的缺点在于

"Hello " + firstName + " " + lastName + ", you are " + age + " years old.";

"Line1\nLine2\nLine3";

于是就有了模板字符串（Template Literal），它是一种字符串字面量的新形式：

const name = "Kayn";
console.log(`My name is ${name}`);

这样写的好处在于

`Hello ${firstName} ${lastName}, you are ${age} years old.`;

`Line1
Line2
Line3`;

`Next year, you'll be ${age + 1} years old.`;
