本地文件重命名

import fs from 'node:fs';
import path from 'node:path';
function* traverseDirectory(dirPath) {
    const dirEntries = fs.readdirSync(dirPath, { withFileTypes: true });
    dirEntries.sort((a, b) => a.name.localeCompare(b.name, 'en'));
    for (const dirEntry of dirEntries) {
        const fileName = dirEntry.name;
        const pathName = path.join(dirPath, fileName);
        if (dirEntry.isDirectory()) {
            yield* traverseDirectory(pathName);
        }
        else {
            yield pathName;
        }
    }
}
for (const filePath of traverseDirectory('temp')) {
    const ext = path.extname(filePath).slice(1);
    if (ext === 'js') {
        fs.rename(filePath, filePath.replace(/.js/, '.ts'), (err) => {
            if (err) throw err;
            console.log(filePath + ' rename complete');
        });
    }
}

输入目录名称，递归遍历文件，使用 generator 来返回为文件的路径名，并使用 fs.rename 来对文件进行重命名。
