JackedProgrammer, Thanks for making something seemingly difficult easy. I've been waiting for a series like yours. No yelling, no drama, just to the point and on topic. Thanks again!

@5:48 - the shortcut key combo "Ctrl " and "L" will do a better job than cls or clear, no need to type anything. just hit Ctrl and L at the same time. Works in Linux too.

An excellent explanation of how variables work, in clear English. Thank you so much!

I like it that is slow, because I am a total beginner and your videos are clear and easy to understand. thank you

A bit slow and tedious, but good info. One thing, though; I noticed you always highlight the entire code by hand and then click on Run Section icon. Anyone watch, don't forget that you can click on the Play icon (just to left of Run Section icon, or press >F5< to run the entire code (it that's what you want to do). I'm a keyboard shortcut person - faster than dealing with a separate device. I did like that this GUI allows you to run an individual line, or group of lines, without having to wade through the entire list of previous commands.

Your comment toward the end about double being larger, but not a big deal made me feel really old :) I remember (back in the day around, 1712 .. maybe 1579?), where data type could be critical for some larger programs because RAM was so limited - counting the bits for variables and line of code could make or break a project. Not something I miss :)

can someone give solution for this

write a script in PowerShell that reads a configuration from a JSON file and, based
on this configuration, locates selected files. The script accepts one parameter $configfilePath – a
parameter of type string that specifies the path to a configuration file.
Here is an example configuration file:
{
"DirectoryPath": "PATH_TO_DIRECTORY",
"FilesToLocate”: [ "FILE_NAME_1", "FILE_NAME_2"]
}
In the script you should read the configuration and then output the number of files specified by
the FilesToLocate attribute from the given directory specified by the DirectoryPath attribute.
Additional requirements:
You should also meet the following requirements:
• If the path specified by $configPath does not exist, the script should return 1.
• If the DirectoryPath attribute is missing, the script should return 2.
• If the path specified by the DirectoryPath attribute does not exist, or if it is a file, the script
should return 3.
• If the FilesToLocate attribute is missing, the script should return 4.
• If any file provided by the FilesToLocate attribute does not exist, the script should ignore it
and continue processing.
• In the end the script should return the number of files found

When running code on line 3, I get a Visual Studio Code prompt: "connect choices are either " Open 'launch .json' or 'Cancel'"
