Differences

The following are some key differences between JavaScript and Kotlin.

Characteristic	JavaScript	Kotlin
Syntax	JavaScript has a C-style syntax with curly braces, semicolons, and parentheses. It also supports functional programming constructs like anonymous functions and closures.	Kotlin has a similar syntax to Java, but with some added features like null safety and extension functions. It also supports functional programming constructs like lambdas and higher-order functions.
Paradigm	JavaScript is a multi-paradigm language that supports both object-oriented and functional programming styles.	Kotlin is a multi-paradigm language that supports both object-oriented and functional programming styles. It also has some features that make it a good fit for reactive programming.
Typing	JavaScript is a dynamically typed language, which means that variable types are determined at runtime.	Kotlin is a statically typed language, which means that variable types are determined at compile time. It also has support for type inference.
Performance	JavaScript is generally slower than compiled languages like Kotlin, but it has improved significantly with the introduction of new technologies like WebAssembly.	Kotlin is a compiled language that can be optimized for performance. It also has some features that make it a good fit for building high-performance applications.
Libraries and frameworks	JavaScript has a vast ecosystem of libraries and frameworks, including popular ones like React, Angular, and Vue.	Kotlin has a growing ecosystem of libraries and frameworks, including popular ones like Spring and Ktor.
Community and support	JavaScript has a large and active community with many resources available for learning and development.	Kotlin has a growing community with many resources available for learning and development. It is also backed by JetBrains, a company that provides tools and support for developers.
Learning curve	JavaScript has a relatively low learning curve, especially for developers who are already familiar with C-style syntax.	Kotlin has a moderate learning curve, especially for developers who are already familiar with Java or other JVM languages.
