Need TCL/TK learning advice

Hi,

 

I had planned to learn TCL/TK via online tutorial (tutorialpoint). When starting the tutorial, basics are easy to understand. But when getting deeper inside the tutorial after basics, it is very difficult to understand.  So kindly help me with following questions.

 

1) Is there any easy way to learn this language???

 

2) Online tutorials are like in coding format and their teaching also in same way. But written Hyper-mesh scripts are in different way. I am not getting this thing.

 

3) Any suggestion for TCL/TK books, videos and website for learning?

 

Thanks in advance.

 

Regards,
