// 示例JavaScript代码 - 包含各种质量问题用于测试
// 问题1: 使用var而不是let/const
var globalVar = 'should use const';
// 问题2: 硬编码的敏感信息
const API_KEY = 'sk-1234567890abcdef';
const password = 'hardcoded123';
// 问题3: 复杂的函数，高圈复杂度
function complexFunction(x, y, z) {

// 问题4: 潜在的安全漏洞 - eval使用
function dangerousFunction(userInput) {
return eval(userInput);
}
// 问题5: 性能问题 - 字符串拼接

// 问题6: 缺少错误处理
function riskyFunction(data) {
return JSON.parse(data).value.nested.property;
}
// 问题7: 重复代码
function processUserData(user) {

// 问题8: 未使用的变量

// 问题9: 魔法数字

// 问题10: 长参数列表
