Other languages have complex, multi-step setups that beginners often get stuck on. Red has no installer, no setup, no dependencies*, just a single small (~1MB) command-line executable with both the compiler and repl. On Windows, you don't even have to launch executable from the command line--it has a GUI-console.
Question Ranking
Pros
Pro Fast startup
Dash has a very fast startup, this happens because the shell is started a lot of times during boot and dash minimizes the work it does during this process.
Pro Low memory usage, which matters a lot in embedded
It is designed to be very lightweight and has no support for shell specific extensions that are not POSIX.
Pro Default shell on Debian systems
DASH is the default shell for Debian based systems due to it speed, full POSIX compliance and low overhead.
Pro Full POSIX support
It's fully POSIX compatible, so if your script runs on dash it will probably run on all other shells.
Pro A perfect clone
It's a clone of the original System V4 Bourne shell.
Pro Simple toolchain
Other languages have complex, multi-step setups that beginners often get stuck on. Red has no installer, no setup, no dependencies*, just a single small (~1MB) command-line executable with both the compiler and repl. On Windows, you don't even have to launch executable from the command line--it has a GUI-console.
Pro Very simple syntax
Red syntax is a lot like Rebol. It's easier than most languages for beginners to pick up.
Pro Both low and high-level
Red has low enough access to do systems programming, but it's expressive enough for high-level scripting.
Pro Low cognitive load
Red has very simple syntax that's easy to learn. It gets out of your way and lets you think about the problem instead, enhancing productivity.
Cons
Con Doesn't support all bash features
Dash does not support all bash features, sometimes called 'bashisms' unless explicitly pointed at /bin/sh.
Con Not production ready
Red is still under development and not considered stable.
Con Still in beta
It mostly works. It's good enough for building usable applications, but some planned features are missing.
