js string变量赋值

let str1 = 'Hello, World!';
let str2 = "Hello, World!";

let name = 'Alice';
let greeting = `Hello, ${name}!`;

let firstName = 'John';
let lastName = 'Doe';
let fullName = firstName + ' ' + lastName;

// 使用数组的 join 方法
let parts = ['Hello', 'World'];
let result = parts.join(' ');

// 使用模板字符串
let name = 'Alice';
let greeting = `Hello, ${name}!`;

// 使用模板字符串避免转义
let description = `This is a "quote" and a new line.\nThis is on the next line.`;

// 正确转义字符
let description2 = 'This is a "quote" and a new line.\nThis is on the next line.';

// 基本字符串赋值
let str1 = 'Hello, World!';
let str2 = "Hello, World!";

// 模板字符串
let name = 'Alice';
let greeting = `Hello, ${name}!`;

// 字符串拼接
let firstName = 'John';
let lastName = 'Doe';
let fullName = firstName + ' ' + lastName;

console.log(str1); // 输出: Hello, World!
console.log(greeting); // 输出: Hello, Alice!
console.log(fullName); // 输出: John Doe
