id: 1,
icon: '🔍',
name: '代码检查',
simple: '找错误',
detailDesc: '就像写作文前先检查有没有错别字和语法错误。代码检查工具会自动发现你的代码问题,比如变量名拼写错误、漏写了分号、使用了未定义的变量等。',
example: '你写了 const mesage = "hello",检查工具会提醒:"mesage 是不是想写 message?这个变量名看起来有拼写错误。"'
},
{
id: 2,
icon: '⚙️',
name: '代码转换',
simple: '翻译官',
detailDesc: '就像把中文翻译成英文让外国人能看懂。你写的可能是 TypeScript 或新版 JavaScript 语法,但老浏览器"看不懂",需要转换成它们能理解的旧版本。',
example: '你写了 const name = user?.name(新版语法),转换后变成 var name = user && user.name ? user.name : undefined(老浏览器能懂的写法)'
},
{
id: 3,
icon: '📦',
name: '依赖解析',
simple: '理关系',
detailDesc: '就像整理食谱,搞清楚做一道菜需要哪些食材。你的代码可能引用了很多其他文件,这个阶段会分析"谁依赖谁",画出一张完整的关系图。',
example: 'main.js 引用了 utils.jsutils.js 又引用了 helper.js,解析后会生成一张"依赖地图",告诉打包工具按什么顺序处理这些文件。'
},
{
id: 4,
icon: '📚',
name: '模块打包',
simple: '装箱子',
detailDesc: '就像搬家时把零散的东西装进几个大箱子。你的项目可能有上百个文件,浏览器加载太多小文件会很慢,打包就是把它们合并成少数几个文件。',
example: '原来有 100 个 .js 文件,打包后变成 2 个文件:app.js(你的代码)和 vendor.js(第三方库)。浏览器只需请求 2 次而不是 100 次。'
},
{
id: 5,
icon: '✨',
name: '代码优化',
simple: '瘦身',
detailDesc: '就像压缩行李箱,把不必要的东西扔掉。删除代码中的空格和注释、去掉没用到代码(Tree Shaking)、压缩变量名,让文件体积更小。',
example: '原来 100KB 的代码,优化后变成 30KB。比如把 function getUserName() { return name } 压缩成 function a(){return n}'
