Experimental JSEngineNK 1.12.5

Bug fixes and optimization improvements

Now the versions for Java8-11 and Java11-20 were updated (in java11 I recommend using the Java11-20 version)
Added readfully() function to read text files example usage:

JavaScript:

var test = readFully("absolutePath/archive.txt"); //use the absolute Path of the file!

New Polyfills added!
Fixed permission bug for the /scripts command where the command would be seen in players' command list even if they did not have the permission
Arrangement of the last parameter of the given command function (the Command.this class)

The interface was improved a little when starting the plugin
Added an argument to commands after Label that returns the command class of the command
Added a jar for Java15 version and higher!
(Use the corresponding jar with your version of java!)

Fixed the error that code errors did not appear in the Enable event
Fixed bug in Navigator API

What was added?
Permission, Usage and alias arguments were added to the function
More information in the plugin description

Update on the execution of the command function:
Now the Label is passed to the function that executes the command
More information in the plugin information

And it can also continue to be used even if no alias or permission is defined.
Like if Label in function to avoid incompatibility.

String:
includes
padStart
padEnd

Array:
flatMap

Object:
is
values
getOwnPropertyDescriptors

Added event PlayerFormRespondedEvent
Many Polyfills, Libraries, etc. are added.
Example:
.replaceAll();
Promises, etc. You can see most of them in the implemented libraries in the description
In addition, the loading of Libraries by URL to another function was eliminated so that it works through Maven
