Differences

The following are some key differences between COBOL and Kotlin.

Characteristic	COBOL	Kotlin
Syntax	COBOL uses a verbose and English-like syntax.	Kotlin uses a concise and modern syntax.
Paradigm	COBOL is primarily procedural and imperative.	Kotlin is a statically-typed, object-oriented language that also supports functional programming.
Typing	COBOL is statically-typed.	Kotlin is statically-typed with type inference.
Performance	COBOL is known for its efficiency and performance in handling large-scale business applications.	Kotlin is a modern language that aims for good performance, but it may not be as optimized for specific business use cases as COBOL.
Libraries and frameworks	COBOL has a limited number of libraries and frameworks available compared to modern languages like Kotlin.	Kotlin has a wide range of libraries and frameworks available, making it easier to build various types of applications.
Community and support	COBOL has a smaller and more specialized community compared to Kotlin.	Kotlin has a large and active community with extensive support from JetBrains and the Kotlin Foundation.
Learning curve	COBOL has a steeper learning curve due to its verbose syntax and specialized use cases.	Kotlin has a relatively gentle learning curve, especially for developers familiar with Java or other statically-typed languages.
