When comparing Scratch vs Tcl, the Slant community recommends Scratch for most people. In the question“What is the best programming language to learn first?” Scratch is ranked 13th while Tcl is ranked 29th. The most important reason people chose Scratch is:
Code is represented as [visual building blocks](http://www.instructables.com/id/How-to-use-Scratch/) that makes it easy to understand how a program is put together.

Code is represented as visual building blocks that makes it easy to understand how a program is put together.
Pro Easy to learn
Scratch is designed to teach computational thinking rather than focus on specific syntax. It was designed specifically to be easy to learn for anyone over the age of 8.
Pro Great starting point for kids
Scratch was developed specifically for kids ages 8 and up as an exciting way to introduce them to technology. It's designed to be easy to learn, but still provides good depth in computational thinking.
Pro No need to be able to type
Pro Can be used to create games
Pro Highly structured
The language is highly structured. Therefore, it gives you the essentials of how to think like a programmer and teaches you good programming practices from early on, so you could write clean, working and readable code in the future.
Pro Widely available
You can expect a reasonably recent version of Tcl to either installed or available in the repositories of any popular open source *nix.
Pro Standard library
Unlike *sh Tcl has a rich standard library.
With a little care you can have the same script work on Linux, *BSD, OS X and Windows.
Pro Tk and Expect
Pro Everything is a string
Tcl can operate at the same level of abstraction as the POSIX shell, which makes it easier to manipulate the output of other programs.
Pro Sane quoting rules
Unlike in *sh you don't need to quote your variable substitutions ('"$1"').
Con Won't get you a job
Scratch is not a language used in the workplace. Instead it teaches computational thinking, helping to create a foundation to aid in learning other languages.
Con Does not teach you programming
Learning Scratch might help you if you have high difficulty with logical thinking. However, starting with a proper programming language, especially an easy one, will give you the benefits of starting with something like Scratch and everything else.
