Building a Traffic Light System in Julia Programming Language
create-quick-stack is a command line tool designed to streamline the initial setup of JavaScript projects. This CLI tool interactively guides you to set up a new project, helping you choose the web development framework and libraries your project requires.
A simple traffic light simulator written in the Julia programming language. The program will output the current light color and how long it will stay that color. The program will continue to cycle through the lights until the program is stopped.
I've been learning Julia and this seemed like a fun project to create.
Julia was designed from the beginning for high performance. Julia programs compile to efficient native code for multiple platforms via LLVM.
Julia is dynamically typed, feels like a scripting language, and has good support for interactive use.
Reproducible environments make it possible to recreate the same Julia environment every time, across platforms, with pre-built binaries.
Julia uses multiple dispatch as a paradigm, making it easy to express many object-oriented and functional programming patterns. The talk on the Unreasonable Effectiveness of Multiple Dispatch explains why it works so well.
Julia provides asynchronous I/O, metaprogramming, debugging, logging, profiling, a package manager, and more. One can build entire Applications and Microservices in Julia.
Julia is an open source project with over 1,000 contributors. It is made available under the MIT license. The source code is available on GitHub.
