本文的目的是为了博您一乐,如果您觉得被冒犯了,可以在评论区骂我,这样我会获得比较多的经验值。先谢谢了!
初级水平:
作为初学者,开发者可能更多地依赖于基本的条件语句和字符串连接。
javascript
let target;
if (queryParams) {
target = baseUrl + '?' + queryParams;
} else {
target = baseUrl;
}
中级水平:
中级开发者可能会使用更简洁的方法,如三元运算符进行条件判断,并可能开始使用模板字面量进行字符串连接。
javascript
const target = queryParams ? baseUrl + '?' + queryParams : baseUrl;
高级水平:
高级开发者会追求最大的简洁性和可读性,可能会充分利用模板字面量。他们还可能考虑未来的可维护性和潜在的边缘情况。
javascript
const target = `${baseUrl}${queryParams ? `?${queryParams}` : ''}`;
专家水平:
专家开发者不仅编写简洁的代码,还会考虑代码使用的更广泛背景,包括可扩展性和潜在的边缘情况。
javascript
const target = `${baseUrl}${queryParams && Object.keys(queryParams).length > 0 ? `?${queryParams}` : ''}`;
在这个版本中,专家级开发者确保只有当查询参数存在且不是空对象时才附加它们。这个检查防止了在没有实际参数的情况下不必要地附加问号。
大师水平:
大师级开发者会思考代码超出其应用范围的事情,考虑重用性、功能性以及与系统其他部分的潜在集成。
javascript
const buildUrl = (base, params) => `${base}${params && Object.keys(params).length ? `?${params}` : ''}`;
// 使用方法
const target = buildUrl(baseUrl, queryParams);
在这个等级上,开发者将逻辑抽象为一个可重用的函数 buildUrl
,增强了代码的可重用性和可维护性。这个函数可以轻松地进行测试、维护,并在应用的不同部分甚至跨项目中重用。大师级开发者在考虑干净的架构、可维护性和潜在的未来需求方面思维广阔。
Five Levels Developer When Implement One Function
Beginner Level:
As a beginner, a developer might rely more on basic conditional statements and string concatenation.
javascript
let target;
if (queryParams) {
target = baseUrl + '?' + queryParams;
} else {
target = baseUrl;
}
Intermediate Level:
An intermediate developer would likely use more concise methods like the ternary operator for conditionals and might start using template literals for string concatenation.
javascript
const target = queryParams ? baseUrl + '?' + queryParams : baseUrl;
Advanced Level:
An advanced developer would aim for maximum conciseness and readability, likely employing template literals to their full extent. They may also consider future maintainability and potential edge cases.
javascript
const target = `${baseUrl}${queryParams ? `?${queryParams}` : ''}`;
Expert Level:
An expert developer not only writes concise code but also considers the broader context in which the code will be used, including scalability and potential edge cases.
javascript
const target = `${baseUrl}${queryParams && Object.keys(queryParams).length > 0 ? `?${queryParams}` : ''}`;
In this version, the expert developer ensures that the query parameters are only appended if they exist and are not an empty object. This check prevents unnecessary appending of a question mark without any actual parameters.
Master Level:
A master-level developer thinks beyond the code to its application, considering aspects like reusability, functionality, and potential integration with other parts of the system.
javascript
const buildUrl = (base, params) => `${base}${params && Object.keys(params).length ? `?${params}` : ''}`;
// Usage
const target = buildUrl(baseUrl, queryParams);
