Key differences between Kotlin and JavaScript

CharacteristicKotlinJavaScript
SyntaxKotlin has a concise and expressive syntax that is similar to Java but with some added features such as null safety and extension functions.JavaScript has a more flexible and dynamic syntax that allows for more creative coding styles, but can also lead to more errors and bugs.
ParadigmKotlin is a statically-typed, object-oriented language that also supports functional programming concepts.JavaScript is a dynamically-typed, object-oriented language that also supports functional programming concepts.
TypingKotlin is a statically-typed language, which means that variables must be declared with a specific data type at compile time.JavaScript is a dynamically-typed language, which means that variables can change data types at runtime.
PerformanceKotlin is generally faster than Java because it is more concise and has better type inference.JavaScript can be slower than other languages because it is interpreted rather than compiled.
Libraries and frameworksKotlin has a growing number of libraries and frameworks, including Spring Boot and Ktor.JavaScript has a vast ecosystem of libraries and frameworks, including React, Angular, and Node.js.
Community and supportKotlin has a growing community and is backed by Google, which provides strong support.JavaScript has a massive community and is supported by many companies, including Google, Facebook, and Microsoft.
Learning curveKotlin has a relatively low learning curve for Java developers because it is similar to Java in many ways.JavaScript has a steep learning curve due to its flexible syntax and many quirks and gotchas.
