我有以下Ecma-Script-6代碼 template literalslet person = {name: 'John Smith'};   let tpl = `My name is ${person.name}.`;    let MyVar="My name is "+ person.name+".";console.log("template literal= "+tpl);  console.log("my variable = "+MyVar);輸出如下：template literal= My name is John Smith.my variable = My name is John Smith.這是小提琴。我嘗試搜索確切的差異，但找不到它，我的問題是這兩個語句之間有什么區別，  let tpl = `My name is ${person.name}.`;    和  let MyVar = "My name is "+ person.name+".";我已經可以在此處將字符串MyVar串聯起來person.name了，那么使用模板文字的方案是什么？
