JavaScript ES6 字符串的格式化

向右看齐 2023-07-23 12:55 11阅读 0赞

JavaScript ES6 之前的标准，是无法格式化字符串的，想要拼接字符串只能使用 +

JavaScript ES6 支持在字符串中使用 $\{变量名\} 拼接字符串，使用处会自动替换。具体使用如下：

var name = 'ConstXiong';
    var es5Str = 'I am ' + name;
    var es6Str = `I am ${name}`;
    console.log(es5Str);
    console.log(es6Str);
    //均输出 "I am ConstXiong"
