字节数组:字节数组是由一系列字节组成的数据结构。在JavaScript中,可以使用Uint8Array或Buffer来表示字节数组。 文件写入:文件写入是指将数据写入到文件中。在Node.js中,可以使用fs模块的writeFile()方法来实现文件写入操作。 JavaScript中的Buffer:Buffer是Node.js中用于处理二进制数据的类。它可以用来

// write a buffer await fsx.write("/path/to/file.txt", buffer); 作为额外的好处,fsx.write()将自动创建任何尚不存在的目录。这是我经常遇到的另一个问题,我认为它应该在现代文件系统 API 中“正常工作”。 使用fsx 检测文件 要确定一个文件是否存在,使用fsx.isFile(filePath)方法,如果给定的文件存在,...

JavaScript Array: Exercise-21 with Solution Flatten Nested Array Write a JavaScript program to flatten a nested (any depth) array. If you pass shallow, the array will only be flattened to a single level. Sample Data: console.log(flatten([1, [2], [3, [[4]]],[5,6]])); ...
