javascript - 如何查看目录？

Question

我有一段代码用于检查 .json 是否存在。我需要代码仅在特定文件夹中查找 .json 。我该怎么做？

if (extName === '.json') { 
    const fullFileNamed = '../../theme-default/resource/i18n'
    // console.log (fullFileNamed, "fullFileNamed")

    if(fullFileNamed) {
      console.log ( fullFileNamed, "fullFileNamed")
      const fileContent = fs.readFileSync(fullFileName, 'utf8')
      console.log (fileContent, "fileContent")
    } 
}   

这个如果不正确。怎样做才是正确的？

if 条件没问题，const fileContent = fs.readFileSync(fullFileName, 'utf8') 中的变量名称拼写错误，应将其更正为 const fileContent = fs.readFileSync(fullFileNamed, 'utf8')

if (extName === '.json') { 
    const fullFileNamed = '../../theme-default/resource/i18n'
    // console.log (fullFileNamed, "fullFileNamed")

    if(fullFileNamed) {
      console.log ( fullFileNamed, "fullFileNamed")
      const fileContent = fs.readFileSync(fullFileNamed, 'utf8')
      console.log (fileContent, "fileContent")
    } 
}
