The system creates a screen buffer whenever it creates a new console. To open a handle to a console's active screen buffer, specify the CONOUT$ value in a call to the CreateFile function. A process can use the CreateConsoleScreenBuffer function to create additional screen buffers for its console.
Its cursor is visible and positioned at the buffer's origin (0,0), and the window is positioned with its upper left corner at the buffer's origin. The size of the console screen buffer, the window size, the text attributes, and the appearance of the cursor are determined by the user or by the system defaults.
The console.log() is a function in JavaScript which is used to print any kind of variables defined before in it or to just print any message that needs to be displayed to the user. Syntax: console.log(A); Parameters: It accepts a parameter which can be an array, an object or any message. Return value: It returns the value of the parameter given.
The properties associated with a screen buffer include: Screen buffer size, in character rows and columns. Text attributes (foreground and background colors for displaying text to be written by the WriteFile or WriteConsole function).
toString('hex') works great! My example splits every 2 characters for easier visual parsing.
buf.toString('hex').match(/../g).join(' ')
