Java vs TypeScript: What are the differences?

Java and TypeScript are both popular programming languages that are widely used for building software applications. Let's explore the key differences between them.

Syntax and Static Typing: TypeScript is a superset of JavaScript and supports static typing, meaning that variables must be declared with a specific data type. On the other hand, Java has its own syntax and enforces strong static typing, which requires explicit declaration of variable types.
Platform Dependence: Java is platform-independent, as it can run on any machine with a Java Virtual Machine (JVM). TypeScript, on the other hand, is designed to run on JavaScript engines, and therefore is platform-dependent.
Compilation vs Interpretation: Java is a compiled language, which means that the source code is compiled into bytecode that can be executed by a Java Virtual Machine. In contrast, TypeScript is transpiled to JavaScript, which is then interpreted by the JavaScript engine.
Object-Oriented Paradigm: Both Java and TypeScript support object-oriented programming, but they have different approaches. Java follows a class-based inheritance model, where classes define the structure and behavior of objects. TypeScript, on the other hand, supports prototypal inheritance and also introduces additional features like interfaces and generics.
Tooling and Ecosystem: Java benefits from a mature and extensive tooling and ecosystem, with various integrated development environments (IDEs), libraries, and frameworks available. TypeScript, being a younger language, has a growing ecosystem with tooling support from popular IDEs such as Visual Studio Code and an expanding collection of libraries and frameworks.
Runtime Performance: Java is known for its high runtime performance, thanks to its optimized bytecode execution and just-in-time (JIT) compilation. TypeScript, being transpiled to JavaScript, has a performance trade-off as it relies on the efficiency of the JavaScript engine.

In summary, Java is a versatile and widely used programming language known for its platform independence, strong typing, and extensive ecosystem, making it suitable for building scalable and robust enterprise applications. TypeScript is a superset of JavaScript that introduces static typing, providing improved tooling and maintainability for large-scale web development projects, particularly when using modern frameworks like Angular.

Building cool things on the internet 🛠️ at Stream

Sep 5, 2019

Review

I work at Stream and I'm immensely proud of what our team is working on here at the company. Most recently, we announced our Android SDK accompanied by an extensive tutorial for Java and Kotlin. The tutorial covers just about everything you need to know when it comes to using our Android SDK for Stream Chat. The Android SDK touches many features offered by Stream Chat – more specifically, typing status, read state, file uploads, threads, reactions, editing messages, and commands. Head over to https://getstream.io/tutorials/android-chat/ and give it a whirl!

Decided

When developing a new blockchain, we as a team chose Go lang over Java and other candidates, due to Go being (a) natively suited to concurrency - there are primitives in the language itself (goroutines, channels) that really help with reasoning about concurrency (b) super fast - build time, running, testing are all much faster that Java, this gives a far superior developer experience (c) shorter and stricter than Java - code is much shorter (less verbose), and there is usually one good way to do things, and even the code formatter that is bundled with Go is very opinionated - over a short time this makes reading other people's code far smoother than having to deal with different styles.

You should be aware that Go presently (v1.13) lacks Generics.

Decided

Node.js has been growing in popularity, and the ability to access the global pool of Javascript developers is great. There is a decreased amount of effort for people to work across the frontend and backend, and the language itself is easy and works well for many common use cases.

Go was the other serious candidate, but it just hasn't been implemented in as many Production systems yet, and the best Go engineers I've known have been hackers, whereas we're building a robust analytics platform that requires more caution. Type safety is easily added with TypeScript, and NPM is awesomely handy.

Detailed Comparison

Java	TypeScript
Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!	TypeScript is a language for application-scale JavaScript development. It's a typed superset of JavaScript that compiles to plain JavaScript.

What are some alternatives to Java, TypeScript?

JavaScript

JavaScript is most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic,and supports object-oriented, imperative, and functional programming styles.

Python

Python is a general purpose programming language created by Guido Van Rossum. Python is most praised for its elegant syntax and readable code, if you are just beginning your programming career python suits you best.

PHP

Fast, flexible and pragmatic, PHP powers everything from your blog to the most popular websites in the world.

Ruby

Ruby is a language of careful balance. Its creator, Yukihiro “Matz” Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming.

Golang

Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.

HTML5

HTML5 is a core technology markup language of the Internet used for structuring and presenting content for the World Wide Web. As of October 2014 this is the final and complete fifth revision of the HTML standard of the World Wide Web Consortium (W3C). The previous version, HTML 4, was standardised in 1997.

C#

C# (pronounced "See Sharp") is a simple, modern, object-oriented, and type-safe programming language. C# has its roots in the C family of languages and will be immediately familiar to C, C++, Java, and JavaScript programmers.

Scala

Scala is an acronym for “Scalable Language”. This means that Scala grows with you. You can play with it by typing one-line expressions and observing the results. But you can also rely on it for large mission critical systems, as many companies, including Twitter, LinkedIn, or Intel do. To some, Scala feels like a scripting language. Its syntax is concise and low ceremony; its types get out of the way because the compiler can infer them.

Elixir

Elixir leverages the Erlang VM, known for running low-latency, distributed and fault-tolerant systems, while also being successfully used in web development and the embedded software domain.

Swift

Writing code is interactive and fun, the syntax is concise yet expressive, and apps run lightning-fast. Swift is ready for your next iOS and OS X project — or for addition into your current app — because Swift code works side-by-side with Objective-C.
