// =============================================================================
// 工具函数
// =============================================================================
// 延迟函数（避免与系统sleep冲突）
function delay(ms) {
var start = new Date().getTime();
while (new Date().getTime() < start + ms) {
// 等待
}
}
// =============================================================================
// 第一部分：基础函数示例
// =============================================================================
// 简单函数定义
function greet(name) {
return "你好, " + name + "!";
}
// 带默认参数的函数
function greetWithDefault(name) {
var defaultName = "用户";
if (name === undefined || name === null) {
name = defaultName;
}
return "你好, " + name + "!";
}
// 多参数函数
function calculateArea(width, height) {
return width * height;
}
// 演示基础函数
function demoBasicFunctions() {
console.log("=== 基础函数示例 ===");
var greeting = greet("张三");
console.log(greeting);
var defaultGreeting = greetWithDefault();
console.log(defaultGreeting);
var area = calculateArea(5, 10);
console.log("矩形面积: " + area);
}
// =============================================================================
// 第二部分：返回值与条件返回
// =============================================================================
// 返回单个值
function getMaxValue(arr) {
if (!arr || arr.length === 0) {
return null;
}

}
// 条件返回示例

return "错误: 除数不能为零";
}

}
// 演示返回值函数
function demoReturnValues() {

},
