Not able to exit from the powershell console after script execution - windows

Question

I am trying to create a script for my class to automatically create a folder monthDay wise and open it in Visual Studio Code. However, after the script executes the powershell console remains open until I close it manually or I close VSCode. I just want the console to go away after it executes. Here is the script: Please tell me how to do it..
# Hash table for months
$hash_month = #{1="jan";2="feb";3="mar";4="apr";5="may";6="june";7="july";8="aug";9="sep";10="oct";11="nov";12="dec"}
#extracting date
$date = (Get-Date).Day
#extracing month
$month = (Get-Date).Month
# getting month name from the hash table
$month_name= $hash_month[$month]
# Creating the Directory with monthDate
# This command will create a dir if it does not exist, or it will simply not execute if the directory exists
[System.IO.Directory]::CreateDirectory("$month_name$date")
# changing dir
cd $month_name$date
# opening the dir in vscode
code .
# currently not able to exit from console after execution of script
exit 0
I have attached the screenshot of the window, I just want the console to go away but NOT vscode.

I made 2 changes here:
The path creation is handled differently, which has nothing to do with the question, but your way was not creating the path for me.
Used Start-Process with hidden window to instantiate VSCode and make the $pid kill method work.
Full script:
# Hash table for months
$hash_month = #{1 = "jan"; 2 = "feb"; 3 = "mar"; 4 = "apr"; 5 = "may"; 6 = "june"; 7 = "july"; 8 = "aug"; 9 = "sep"; 10 = "oct"; 11 = "nov"; 12 = "dec" }
#extracting date
$date = (Get-Date).Day
#extracing month
$month = (Get-Date).Month
# getting month name from the hash table
$month_name = $hash_month[$month]
# Creating the Directory with monthDate
# This command will create a dir if it does not exist, or it will simply not execute if the directory exists
$path = $month_name + $date
if (!(Test-Path $path)) {
New-Item $path -ItemType Directory
}
# # changing dir
cd $path
# # opening the dir in vscode with Start-Process
Start-Process -FilePath "code" -ArgumentList "." -WindowStyle Hidden
# # currently not able to exit from console after execution of script
Stop-Process $pid
