Byebug Cheatsheet

This cheatsheet includes most of the byebug commands organized by related commands (e.g. breakpoint related commands are together).

To see official help...

Command	Aliases	Example	Comments
help	h	h	list top level of all commands
help cmd	h cmd-alias	h n	list the details of a command (example shows requesting details for the next command) (this works for all commands)

I am passionate about Ruby, but its execution time compared to other languages is extremely high, especially when we want to use more complex algorithms. In general, data structures in interpreted languages become incredibly slow compared to compiled languages. Some algorithms such as ´n-body´ and ´fannkuch-redux´ can be up to 30 times slower in Ruby than Go. This is one of the reasons I was interested in embedding Go code in a Ruby environment.

For those who do not know how shared libraries operate, they work in a similar way as DLLs in Windows. However, they have a native code with a direct interface to the C compiler.

Note Windows uses the DLL system, and in this case, this does not necessarily have to be in native code.

One example is DLLs written in C#, which runs on a virtual machine. Because I do not use windows, I ended up not testing if it is poss
