# 描述
issue专用，用于展示rspack处理ts/js时发生的问题
# 项目执行
```shell
$ npm run build
```
## rspack打包前
```JS
// src/index.ts
const xhr = {
responseType: false,
responseText: "OK",
response: {}
}
console.log(
( xhr.responseType || "text" ) !== "text" ||
typeof xhr.responseText !== "string" ?
{ binary: 1 } :
{ text: 2 }
)
// 条件一 和 条件二 均为false，因此实际应该打印 { text: 2 }
```
## 打包后
```JS
// dist/main.js
var xhr = {
responseType: false,
responseText: "OK",
response: {}
};
console.log((xhr.responseType || "text") !== "text" || 0 ? { // 语句：`typeof xhr.responseText !== "string"` 被转为 0
binary: 1
} : 0) // 此处打印{ binary: 1 } 或 0，结果都不对；
```
