Python is among the 3 most flexible programming languages across the globe (the other two being Java and C++). It's used almost anywhere for almost anything. It is extremely powerful in the financial sector and in numerical analysis, robotics, IoT, natural language processing, web services, big data, business management, gaming backends, neuroscience, telephony infrastructure, animation, media storage and processing, and so on.

For the time being, Javascript seems to be the only front-end language on the internet, so people are stuck onto it, and with the help of Node, it's expanding rapidly into the back-end too. That looks promising because it's just easier to use the same language for both front-end and back-end development. Also, they've been developing the JS standard to refine it and make the process even easier.

Let’s have a look at some of the factors we can use to make the decision to choose between Python and Javascript:

Performance

Comparing Node.JS, a massive JavaScript ecosystem, and Python's smart efficiency, the former is clearly much faster. It is because it uses the Google V8 JavaScript and WebAssembly engine, which is an amazingly fast and dynamic engine.

Furthermore, with its high performance and speed, Node.js is the optimal option for applications featuring real-time messaging or chatting, as well as for heavy-duty applications, content management systems, Multi-vendor marketplaces, e-commerce solutions, and, to a greater extent, processing speed.

User-friendliness

Python is a programming language that is somewhat the best beginner's option, particularly for those who do not have any programming experience.

A few qualities that make Python an easy-to-use language are:

High readability Python code
Fewer lines of code compared to C and C++ languages.
Fewer structural guidelines and constraints
Availability of various frameworks containing pre-written code to speed up the execution of the project.

Compared to Python, JavaScript is difficult, and here's why:

Hard to debug
More structural rules and additional characters

Although Python vs JavaScript , Python defeats JavaScript in data science and user-friendliness, JavaScript outperforms Python in front-end development and efficiency.

We may assume that each of these languages will reign over the coming years, but in their particular fields – Python will play a prominent role in fields like machine learning, data science, and neural networks, while JavaScript will conquer the world of web development comprising real-time applications.

To Conclude…

Python is typically a beginners-choice, particularly for those who have no significant programming knowledge.

Python code is known for being more readable, which means it's easier to understand (and write).
The code in Python has fewer lines than in other languages like C or C++.
There are fewer structural rules in Python. For example, after each sentence, you are not required to write a semicolon.
There are several frameworks that include pre-written code to speed up the creation of your projects.

However, although being easy to learn, Python needs some strong navigational skills.

JavaScript is the most common language, but it isn't that simple to understand.

One critical point is that JavaScript is hard to debug. You might find that although your code is absolutely error-free, the program doesn't run.
There are several more characters, such as curly brackets and semicolons. However, in the latest versions of JS, the semicolons would occur automatically.
One advantage is that the JavaScript syntax is similar to the principles of other C-like languages. People with expertise in such languages would also be more prepared to learn JavaScript.

To conclude, it's often better to master the language that stimulates and fascinates you. In addition, do not believe that you will become a master of programming just by reading about them. It is more essential to work on real-life projects with strong goals, to identify potential
options and to choose the most appropriate ones.
