Key differences between COBOL and Kotlin

CharacteristicCOBOLKotlin
SyntaxCOBOL uses a verbose and English-like syntax.Kotlin uses a concise and modern syntax.
ParadigmCOBOL is primarily procedural and imperative.Kotlin is a statically-typed, object-oriented language that also supports functional programming.
TypingCOBOL is statically-typed.Kotlin is statically-typed with type inference.
PerformanceCOBOL 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 frameworksCOBOL 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 supportCOBOL 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 curveCOBOL 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.
