${variable_name}用作变量插值

您还可以使用模板字面量执行隐式类型转换。 例子:

let fruits = ["mango","orange","pineapple","papaya"];

console.log(`My favourite fruits are ${fruits}`);
// My favourite fruits are mango,orange,pineapple,papaya

它用于引用字符串中的变量:

let someVar = "World!"
console.log(`Hello ${someVar}`); // Output is Hello World!

const firstName = 'Sachin'; Const age = 16 alert(${firstName}为${age}岁)

//Sachin今年16岁

正如上面的注释中提到的，你可以在模板字符串/字面量中包含表达式。例子:

Const 1 = 1; Const 2 = 2; const result = '一加二是${一+二}'; console.log(结果);// output: 1加2等于3
