Key differences between C and Nim

CharacteristicCNim
SyntaxProcedural, uses braces for code blocks, semicolons to end statements, and a minimalistic, low-level syntax.Python-like, indentation-based syntax, more modern and readable, supports advanced constructs like templates and macros.
ParadigmProcedural and structured programming.Multi-paradigm: supports procedural, object-oriented, functional, and metaprogramming.
TypingStatic, weak typing with manual memory management.Static, strong typing with type inference and optional garbage collection.
PerformanceVery high, close to hardware, minimal abstraction.Comparable to C, compiles to C, C++, or JavaScript, with some overhead from abstractions.
Libraries and frameworksExtensive, mature ecosystem, but many libraries are low-level.Smaller ecosystem, but can use C libraries directly; growing number of native Nim libraries.
Community and supportLarge, established, with decades of resources and support.Smaller, but active and growing community; less mature support.
Learning curveSteep, especially due to manual memory management and low-level concepts.Gentler, more approachable syntax and modern features, but some complexity in advanced features.
