Artificial Intelligence and Data Science are the technologies of the future. Companies are actively hiring tech professionals with skills in mainstream languages which include Java, JavaScript, Ruby, Python, PHP, C#, C++, and Objective-C. The emerging ones like Go, Scala, Swift, Clojure, Haskell also have applicability. Here are new programming languages picking up popularity among AI, ML developers.

1. Ballerina
This programming language was developed as an alternative to configuration-based integration tools. It is one of the first languages that use constructs designed for cloud-native development. Ballerina is influenced by the syntax from Java, Go, and JavaScript. The scripting of this language is easy to learn, write, and modify.

2. Kotlin
The open-source programming language is adopted by Google as an official programming language. Kotlin was first developed by JetBrains, who are makers of IntelliJ IDEA IDE. The interoperability between Java and Koltin makes it popular among mobile app developers. Several apps are rewritten in Kotlin since it addresses the major issues.

3. Dart
The object-oriented programming language by Google is aimed at mobile devices and web development. Dart tops the list of fastest-growing programming languages. The cross-platform mobile app development framework, Flutter is based on Dart.

4. TypeScript
The open-source programming language was developed by Microsoft in 2012. TypeScript allows users to report bugs and use the same type of system to create code. Typescript comes with its own optional static type system that allows users to write dynamically or mix both types of code.

5. Crystal
The programming language is considered as the younger sister of Ruby. More than 300 contributors with strong influence from Ruby have developed Crystal. The free and open-source programming language is easy to read and write. Developers with experience in Ruby can easily get started with Crystal.
