JavaScript vs Objective-C vs Python: What are the differences?

<JavaScript, Objective-C, and Python are three popular programming languages used for various software development projects. In this analysis, we will highlight the key differences between JavaScript, Objective-C, and Python.>

  1. Syntax and Typing: JavaScript is a dynamically-typed language with loose syntax rules, allowing for flexibility but potentially leading to errors at runtime. Objective-C is a statically-typed language with a strict syntax structure, ensuring type safety and catching potential errors during compilation. Python is dynamically-typed like JavaScript but has a more readable and concise syntax compared to JavaScript’s curly brace syntax.

  2. Platform Compatibility: JavaScript is primarily used for front-end web development and can run in any web browser without additional setup. Objective-C is mainly used for macOS and iOS app development, limited to Apple’s ecosystem. Python is a versatile language that can run on various platforms including Windows, macOS, and Linux, making it easy to work across different operating systems.

  3. Performance: JavaScript, being an interpreted language, may suffer from slower performance compared to compiled languages like Objective-C. Objective-C, due to its compile-time optimization, typically offers better performance for resource-intensive tasks. Python, as an interpreted language, tends to be slower than compiled languages, but its simplicity and ease of use make it a preferred choice for quick development.

  4. Concurrency and Parallelism: JavaScript has limited support for proper concurrency and parallelism due to its single-threaded nature, mainly relying on asynchronous programming techniques. Objective-C provides robust support for multithreading and parallel computing through Grand Central Dispatch. Python’s Global Interpreter Lock (GIL) limits true parallelism, making it challenging to fully utilize multiple CPU cores for parallel processing.

  5. Community and Ecosystem: JavaScript has a vast and active community with a rich ecosystem of libraries and frameworks for web development, giving developers access to a wide range of tools. Objective-C has a smaller community compared to JavaScript but is well-supported within the Apple development community, offering specialized resources for macOS and iOS development. Python boasts a large community and extensive library support for various applications, including data science, machine learning, web development, and automation.

  6. Learning Curve: JavaScript has a relatively low learning curve, making it accessible for beginners and ideal for front-end web development. Objective-C, with its strict syntax and concepts like memory management, can be more challenging for beginners, especially those new to object-oriented programming. Python’s simple and readable syntax makes it beginner-friendly, suitable for those starting in programming or wanting to quickly build prototypes.

In Summary, JavaScript, Objective-C, and Python differ in syntax and typing, platform compatibility, performance, concurrency, community support, and learning curve, catering to various development needs and preferences.

Decided

In December we successfully flipped around half a billion monthly API requests from our Ruby on Rails application to some new Python 3 applications. Our Head of Engineering has written a great article as to why we decided to transition from Ruby on Rails to Python 3! Read more about it in the link below.

Needs adviceonReact NativeReact NativePythonPythonFlutterFlutter

I've been juggling with an app idea and am clueless about how to build it.

A little about the app:

  • Social network type app ,
  • Users can create different directories, in those directories post images and/or text that'll be shared on a public dashboard .

Directory creation is the main point of this app. Besides there'll be rooms(groups),chatting system, search operations similar to instagram,push notifications

I have two options:

  1. React Native, Python, AWS stack or
  2. Flutter, Go ( I don't know what stack or tools to use)

Decided

We decided to use python to write our ETLs and import them into metabase via a lambda. Before python we tried using Go, but overall go was way more verbose than Python when writing the ETLs. Go also had some issues managing memory when using the S3 upload manager library. This was a deal breaker for us that made us switch to Python.

In the end the solution was much cleaner and maintainable.

Detailed Comparison

Python

Objective-C
Objective-C
JavaScript
JavaScript

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.

Objective-C is a superset of the C programming language and provides object-oriented capabilities and a dynamic runtime. Objective-C inherits the syntax, primitive types, and flow control statements of C and adds syntax for defining classes and methods. It also adds language-level support for object graph management and object literals while providing dynamic typing and binding, deferring many responsibilities until runtime.

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.

What are some alternatives to Python, Objective-C, JavaScript?

PHP

PHP

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

Ruby

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

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

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

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#

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

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

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

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.

Rust

Rust

Rust is a systems programming language that combines strong compile-time correctness guarantees with fast performance. It improves upon the ideas of other systems languages like C++ by providing guaranteed memory safety (no crashes, no data races) and complete control over the lifecycle of memory.
