C++ vs Erlang: What are the differences?

Key difference 1: Syntax and language features C++ is a statically typed language that provides support for object-oriented programming, allowing the use of classes and objects for structuring code. It has a complex syntax with a large number of language features, including pointers, templates, and operator overloading. On the other hand, Erlang is a dynamically typed language that focuses on concurrency, fault-tolerance, and distributed computing. It has a simpler syntax with built-in support for message-passing concurrency model and pattern matching.
Key difference 2: Memory management C++ requires manual memory management using concepts like new and delete operators to allocate and deallocate memory explicitly. This flexibility comes at the cost of potential memory leaks and dangling pointers if not managed carefully. In contrast, Erlang abstracts away memory management by using a garbage collector that automatically handles memory allocation and deallocation, making it easier to write reliable and safe code.
Key difference 3: Concurrency and parallelism C++ provides support for concurrent programming through libraries like threads and mutexes, but it requires explicit synchronization mechanisms to manage shared data, making it prone to issues like race conditions and deadlocks. Erlang, on the other hand, embraces concurrency as a fundamental feature of the language, using lightweight processes called "actors" that communicate through message passing. It ensures implicit synchronization and isolation of state, making it easier to write highly concurrent and parallel applications.
Key difference 4: Error handling In C++, error handling is typically done through exceptions, which allow for structured error handling and propagation. However, exceptions can have a significant performance impact if thrown frequently and not properly handled. In Erlang, error handling is based on the "let it crash" philosophy, where errors are viewed as normal and expected occurrences. Processes can be easily restarted upon failure, promoting fault-tolerant systems.
Key difference 5: Performance and optimization C++ is often favored for performance-critical applications due to its low-level control over memory and hardware. It allows for manual optimization and fine-tuning of code to achieve maximum performance. Erlang, on the other hand, prioritizes fault-tolerance and scalability over raw performance. It relies on message passing and lightweight processes, which may introduce overhead compared to low-level, highly optimized C++ code.

In Summary, C++ and Erlang differ in terms of syntax and language features, memory management, concurrency models, error handling approaches, and performance priorities. These differences stem from their distinct design goals and target domains, making each language suitable for specific use cases.

Decided

I had a goal to create the simplest accounting software for Mac and Windows to help small businesses in Canada.

This led me to a long 2 years of exploration of the best language that could provide these features:

Great overall productivity
International wide-spread usage for long-term sustainability and easy to find documentation
Versatility for creating websites and desktop softwares
Enjoyable developper experience
Ability to create good looking modern UIs
Job openings with this language

I tried Python, Java, C# and C++ without finding what I was looking for.

When I discovered Javascript, I really knew it was the right language to use. Thinking of this today makes me realize even more how great a decision this has been to learn, use and master Javascript. It has been a fun, challenging and productive road on which I am still satisfied.

Obviously, when I refer to Javascript, it is not without implying the vast ecosystem around it. For me, JS is a whole universe in which almost every imaginable tools exist. It's awesome - for real. Thanks to all the contributors which have made it possible.

To be even clearer about how intense I am with Javascript, let's just say that my first passion was music. Until, I find coding with Javascript! Yep, I know!

So in conclusion, I chose Javascript because it is versatile, enjoyable, widely used, productive for both desktop softwares and websites with ability to create modern great looking user interfaces (assuming HTML and CSS are involved) and finally there are job openings.

Needs adviceon

JavaScript

Python

C++

Hi, I'm just starting to learn code, and I stumbled upon this website. I think I should learn JavaScript, Python, and C++ to begin with. I'm a quick learner so I am only worried about what would be more useful. Suppose my goal is to build an online clothing store or something. Then what languages would be best? I need advice. Please help me out. I'm 13 and just beginning and it's hard to understand when people use technical terms so please keep it simple. Thanks a lot.

Python has become the most popular language for machine learning right now since almost all machine learning tools provide service for this language, and it is really to use since it has many build-in objects like Hashtable. In C, you need to implement everything by yourself.

C++ is one of the most popular programming languages in graphics. It has many fancy libraries like eigen to help us process matrix. I have many previous projects about graphics based on C++ and this time, we also need to deal with graphics since we need to analyze movements of the human body. C++ has much more advantages than Java. C++ uses only compiler, whereas Java uses compiler and interpreter in both. C++ supports both operator overloading and method overloading whereas Java only supports method overloading. C++ supports manual object management with the help of new and delete keywords whereas Java has built-in automatic garbage collection.

What are some alternatives to Erlang, C++?

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.

Java

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!

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.
