Typing	COBOL is statically-typed.	Crystal is statically-typed with type inference.
Performance	COBOL is known for its efficiency and performance in handling large-scale business applications.	Crystal is designed for performance and aims to be as fast as C.
Libraries and frameworks	COBOL has a limited number of libraries and frameworks available compared to modern languages.	Crystal has a growing ecosystem of libraries and frameworks, leveraging the existing Ruby ecosystem.
Community and support	COBOL has a mature community and good support for legacy systems.	Crystal has a smaller but active community with growing support.
