语法错误：意外的令牌

Question

新手编码器在这里！

我在codeacademy.org上学习并继续收到此错误，即使我确信它已被正确写入。帮助

// Declare a variable on line 3 called
// myCountry and give it a string value.
var myCountry = "Panama";
// Use console.log to print out the length of the variable myCountry.
console.log(.length myCountry);

// Use console.log to print out the first three letters of myCountry.
console.log(myCountry .subscript(0,3));

Answer 1

您的示例有两个问题：

console.log(.length myCountry)

不是有效的Javascript;你需要

console.log(myCountry.length)

（length是变量myCountry）的属性。

此外，subscript不是JS函数，您需要substring。

完整示例：

// Declare a variable on line 3 called
// myCountry and give it a string value.
var myCountry = "Panama";
// Use console.log to print out the length of the variable myCountry.
console.log(myCountry.length);

// Use console.log to print out the first three letters of myCountry.
console.log(myCountry.substring(0, 3));

Answer 2

这是正确答案

var myCountry = "myCountry";
console.log("myCountry".length);


var myCountry = "myCountry";
console.log("myCountry".substring(0,3) );
