A first look at the Mojo language #Programming @Infoworld
The newly unveiled Mojo language is being promoted as the best of multiple worlds: the ease of use and clear syntax of Python, with the speed and memory safety of Rust.
Those are bold claims, and since Mojo is still in the very early stages of development, it will be some time before users can see for themselves how the language lives up to them. But Mojo’s originator—a company named Modular—has provided early access to an online playground: a Jupyter Notebook environment where users can run Mojo code and learn about the languages’ features and behavior.
Mojo can be described as a “superset” of Python. Programs written in Python are valid Mojo programs, although some Python behaviors haven’t yet been implemented. Some examples of Python behavior that you won’t currently find in Python are keyword arguments for functions, the global keyword, and list and dict comprehensions. It’s also possible to use the actual Python runtime for working with existing Python modules, although there is a performance cost.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
