Nim vs Lobster

There are generics, templates, macros in Nim. They can allow you to write new DSL for your application, or avoid all boilerplate stuff.

Checks your code at compile time.

With built-in "unittest" module you can create test with a very readable code.

Nim has "asyncdispatch" module, which allows you to write async applications.

Nim has a built-in VM, which executes macros and some other code at compile time. For example, you can check if you're on Windows, and Nim will generate code only for it.

The same code can be used for web, server, desktop and mobile.

Nim has a lot of common with Python in terms of syntax. Indentation-based syntax, for/while loops.

Imperative, OOP, functional programming in one language.

You can use Nim with any language that can be interfaced with C. There's a tool which helps you to create new C and C++ bindings for Nim - c2nim.
Also, you can use Nim with Objective C or even JavaScript (if you're compiling for these backends).

You don't need to deal with all those manual memory allocations, Nim can take care of it. But also you can use another GC, or tweak it for your real-time application or a game.

You only need to specify types in your procedures and objects - you don't need to specify type when you're creating a new variable (unless you're creating it without initialization).

You can use unicode names for variables, there is "unicode" module for operations with unicode.

writeLine(stdout, "hello") can be written as stdout.writeLine("hello")
proc add(a: int): int = a + 5 can be used like 6.add.echo or 6.add().echo()

Unlike Rust doesn't make the programmer jump through hoops, mainly automatic. Does an analysis similar to the Rust borrow checker to infer lifetimes, but makes life easier on the programmer.

There's an audience who loves that.

More options for users.

Structs are allocated in their parent, and come at zero overhead.

Better than Rust. No sadism.

Just works. Goes further than most languages in terms of allowing code without types.
