The example in this article describes how JScript reads and writes binary files. Share to everyone for your reference. The implementation method is as follows:
var bin = new Array (256); for (Var i=0;i
Examples of usage are as follows:

From the file encoding method, the file can be divided into ASCII code files and binary code file two kinds.
ASCII files are also referred to as text files, which are stored on disk with one byte per character for the corresponding ASCII code.

When it comes to thinking of all the files being converted to XML, it's really a good thing. However, this is not true. There are still a large number of file formats that are not XML or even ASCII. The binaries are still propagated across the network, stored on disk, and passed between applications. By contrast, they are more efficient than text files in dealing with these problems.In C and C + +, it is easy to read a binary file. In addition to some
