The PATH is an important concept when working on the command line. It's a list of directories that tell your operating system where to look for programs, so that you can just write script instead of /home/me/bin/script or C:\Users\Me\bin\script. But different operating systems have different ways to add a new directory to it:

Windows

The first step depends which version of Windows you're using:

If you're using Windows 8 or 10, press the Windows key, then search for and

General Tip

"The trick is to catch exceptions at the proper layer, where your program can either meaningfully recover from the exception and continue without causing further errors, or provide the user with specific information, including instructions on how to recover from the error. When it is not practical for a method to do either of these, simply let the exception go so it can be caught later on and handled at the appropriate level."

Excellent example of separating error-handling code from program logic

Three Rules for Effective Exception Handling
Longer explanation and case study of exception use, including the basic principles of "throw early" and "catch late". Clear and thorough.

`__invoke` VS `function` VS `Closure`

This gist is about:

Mainly:

function cannot (should not) be used when side-effects occur
