Tcl (pronounced “tickle”) is a scripting language created in the late 1980s with the goal of being easy to learn and powerful to use. It’s particularly popular in areas like test automation, network programming, and system administration. One of its strengths is how easy it is to integrate with other languages and systems, making it an excellent choice for “gluing” different parts of an application together.

One of the best-known uses of Tcl is with Tk, a GUI toolkit that lets you build graphical interfaces quickly and cross-platform. With just a few lines of code you can create windows, buttons, and other UI elements that work on Windows, macOS, and Linux without changes.

While Tcl may not be the trendiest language today, it has a loyal user base and is still used in many professional contexts. If you need a language for rapid development, simple integration, and powerful scripting capabilities, Tcl is definitely worth exploring.
