This is a Google Apps Script library including useful scripts for supporting to development of applications by Google Apps Script. In the current stage, the 3 categories "For array processing", "For binary processing", and "For string processing" are included in this library.
When I create applications using Google Apps Script, there are useful scripts for often use. At that time, I thought that when those scripts can be simply used, they will be useful not only to me but also to other users. From this motivation, I created a Google Apps Script library including those scripts. But, I have been using these useful scripts only in my development before.
I sometimes answer questions related to Google Apps Script at Stackoverflow. From my experience that I have answered those questions, I also added useful scripts, that I believe, in the library. Some of these scripts will be also the direct answer to the questions. If this was useful for your situation, I'm glad.
The policy of this library is not to use any scopes.

}If you want to use only one method in the above methods without a library, you can do this simply.
In that case, please copy and paste one of the methods from the above scripts. At this time, there are several methods using the other methods. Please copy and paste all dependence methods.
If you want to run the method directly, please remove the identification of the library UtlApp. By this, the script is run.

}I believe that these methods will help to develop the applications created by Google Apps Script. So, I would like to grow this. If you want to add more methods, I welcome your contributions. At that time, please do "pull request" or email me ( [email protected] ). By testing your method, I would like to add it. Your name is also added as a contributor.
The policy of these methods is not to use the scopes. So, when you add your method, please confirm that your proposed method uses no scopes. And also, please check your JSDoc.
