Each of these computer languages has its own pros and cons, so Software Engineers need to know how to use all of them.

Let’s Dig Deeper.


Python is an open-source programming language with several applications. It is commonly used in the fields of web development, AI, data science, and more. Python is an excellent language to learn if you want a career in computer programming or software development.

Because of its easy-to-understand syntax, it belongs to the category of high-level programming languages. Python is often regarded as one of the most accessible programming languages. This language will speed up your learning curve and help you save time in the long term.


  • Readability and Simplicity: Clean syntax of Python makes it easier to read code, which makes it a good choice for both beginners and pros. Its indentation-based style makes sure that everything is the same and cuts down on mistakes.
  • Extensive Libraries: Python has a large standard library and a lot of third-party libraries and tools that make development easier in many different areas.
  • Versatility: Python’s flexibility makes it useful for web development, data analysis, artificial intelligence (AI), and automation. Developers can use the same words in different situations.
  • Rapid Development: Short syntax and strong libraries make it easier to code quickly, which helps projects with tight deadlines and companies that want to make prototypes quickly.
  • Strong Community: The Python community is very active and has a lot of tools, forums, and tutorials to help developers.


  • Performance Limits: Because Python is an interpreted language, it can run slower than compiled languages, which can hurt apps that depend on speed.
  • Global Interpreter Lock (GIL): GIL limits the efficiency of multi-threading, stopping the full use of multi-core processors and slowing down the performance of apps that use multiple threads.
  • Memory Use: Dynamic typing and memory management may cause more memory to be used, which can be a problem for projects that use a lot of memory.
  • Not for Mobile Development: Python is a flexible language, but it’s not the best choice for making mobile apps. Instead, you should use languages like Swift (iOS) and Java/Kotlin (Android).
  • Version Compatibility: When Python moved from Python 2 to Python 3, there were problems with compatibility. This caused a split in the codebases and made it important to move carefully.

According to Indeed, there are currently over 70,000+ jobs with Python and some of them are software engineering jobs.

Javascript is also a significant programming language for software engineers. At its core, JavaScript is used on almost 97% of websites right now. Every front-end or back-end developer needs to know this language. A lot of web applications, systems, and servers also use this language.

JavaScript is a lightweight, interpreted computer language that is most widely recognized as the scripting language for webpages. It is mostly used on the front end to make websites more engaging.

It is a client-side scripting language, which means that the code is run on the user’s machine. This can make the user experience more responsive and keep the server from having to do additional work. But because the code is run on the desktop or laptop of the user, JavaScript can be used to take advantage of security holes by hackersĀ in the browser or machine.


  • Ubiquity: Most browsers support it, which makes it an important part of web creation.
  • Front-End Dominance: This is perfect for developing engaging front-ends and dynamic web content.
  • Rich Ecosystem: There are many frameworks (like React, Angular, and Vue.js) that make programming faster and easier.
  • Asynchronous Programming: lets actions happen without waiting, which makes the user experience better.
  • Support for the community: An active community offers a lot of tools and constant updates.


  • Browser Dependencies: Relies on stability between browsers, which can cause problems.
  • Concerns about security: The fact that client-side scripts can run on it can make it vulnerable.
  • Performance issues: Can be slower than languages that are built locally.
  • Complex, layered callbacks can make code hard to understand and hard to keep up.
  • Lack of Strong Typing: Dynamic typing can cause runtime mistakes that are only caught when the program is being run.

There are now more than 38,000 open positions for Javascript on Indeed:

Our next tech stack is Java, another widely used language in software development. It can be used to create any type of program, including desktop apps, web apps, and even Android apps. There is no limit to what may be accomplished using Java.

Java is one of the most popular programming languages because it is secure by default and is not tied to any one operating system or platform.

You’ll find a lot of help in learning and utilizing Java because of its big and active community.

Its portability and low memory requirements, among other advantages, have contributed to its widespread use. It is platform-agnostic, thus it can be used on any system that supportsĀ Java.


  • Platform Independence: Write once, run anywhere due to Java Virtual Machine (JVM).
  • Robust and Reliable: Strong type checking and handling of exceptions make sure that the program is stable.
  • Large Standard Library: Having a complete library makes development work easier.
  • Support for the community: A strong, active community has a lot to offer.
  • Enterprise Use: Widely used in large-scale applications, backend platforms, and Android app development.


  • Verbose syntax: This language needs more lines of code than some others.
  • Memory Use: Object-oriented programming can cause more memory to be used.
  • Speed Overhead: Depending on how nature is interpreted, speed may be a little bit slower.
  • Boilerplate Code: routinely used snippets of code.
  • Learning Curve: Complexity can be difficult for newcomers to understand at first.

Indeed tells us that there are more than 43,000 open positions related to this language right now.

C++ is a powerful language for making complicated software systems. It is based on the idea of objects. In the early 1980s, Bjarne Stroustrup made it. It adds to the programming language C.

It is often used to code systems, games, and graphics tools. It has been around for a long time and is still one of the most popular Software Engineering computer languages.

C++ is a highly typed language, which can help writers find bugs faster. It’s a fast language that can make code that works well, and there are a lot of writers who can help you if you get stuck. C++ is also cross-platform, so you can build your code for more than one device.

Both languages are middle-level, which means they were designed to be turned into machine code before being run on a CPU. With these languages, users can make small changes to hardware or software. But C isn’t as good for making games or websites with a lot of parts that interact with each other because it doesn’t have object-oriented features like C++ does.


  • Versatility: C++ can be used for many things, from writing at the system level to making games.
  • Performance: It lets you handle memory at a low level, which makes it easier to manage resources.
  • Object-oriented: Allows for object-oriented computing, which makes it easier to organize code into modules.
  • Standard Library: There are a lot of methods and data structures in the rich standard library.
  • group and Resources: There is a strong group of developers and a lot of resources for learning.


  • Complexity: The syntax and features can be hard to understand, which makes the learning curve higher.
  • Memory Management: Memory leaks and bugs are more likely to happen when memory management is done by hand.
  • Compile Time: Compared to languages that are translated or have JIT compilation, compilation can take longer.
  • Problems with Compatibility: Different compilers may handle different languages and act in different ways.
  • Safety Concerns: If there aren’t any built-in safety features, this can lead to mistakes and security holes.

Factors to Consider When Choosing a Programming Language

When starting out as a programmer, one of the most important choices software engineers have to make is which programming language to use. There are several important things to think about when making this choice, and each will have a big impact on their future.
