javascript - 如何在JavaScript中进行字符串插值？(How can I do string interpolation in JavaScript?)

Question

Consider this code:(考虑以下代码：)

var age = 3;

console.log("I'm " + age + " years old!");

Are there any other ways to insert the value of a variable in to a string, apart from string concatenation?(除了字符串连接之外，还有其他方法可以将变量的值插入到字符串中吗？)

Answer 1

Since ES6, you can use template literals :(从ES6开始，您可以使用模板文字 ：)

 const age = 3 console.log(`I'm ${age} years old!`) 

PS Note the use of backticks: `` .(PS请注意反引号的使用： `` 。)
