ParadigmJavaScript is a multi-paradigm language, supporting both object-oriented and functional programming.COBOL is primarily a procedural programming language.
TypingJavaScript is dynamically typed, meaning variable types are determined at runtime.COBOL is statically typed, meaning variable types are determined at compile-time.
PerformanceJavaScript is an interpreted language and generally has lower performance compared to compiled languages like COBOL.COBOL is a compiled language and generally has better performance compared to interpreted languages like JavaScript.
