🧩 What I Should Learn?

• Programming languages for web development

🎯 What I learned today

Programming languages

In the 10-year cycle, 40~50 programming languages are evolving. As a developer, we should choose a language for the desired product that we wish to develop. So, what is suitable for web development?

Low-level languages

As we know, the computer has a switch or transistor to communicate. The computer gets electricity and turns on and off the transistor, representing 0 and 1.

The computer uses a Binary system, and the low-level language means the language that the computer understands. If the developer writes a code with only binary code, which we call a machine language.

But humans can’t understand the machine code easily, so the old developer invented a more developer-friendly programming language.

Of course, the programming language differs from machine language, so we need additional tools to compile this language.

In this process, two more conventions came out. We called the tool compiler and the translating language as Assembly language.

Nowadays, it is difficult to find a program developed in machine or assembly language due to its complicated structure.

High-level languages

Essentially, high-level languages are more human-friendly languages. As the hardware specs increased gradually, the compiler was upgraded.

We can now develop in a readable and human grammar way with these high compiler specs.

We have many high-level languages, including famous languages such as C, Swift, Kotlin, Java, Python and JavaScript.

Less famous languages include Fortran for scientific calculation, Erlang for OTP(Open Telecom Platform) or Lisp.

Most popular languages in web development

• Python: Recommended for beginner developers due to its extremely human-friendly syntax. It is often used in data science and machine learning these days.
• PHP: Still one of the most popular languages in web development. The research from W3Techs shows that 77% of websites used PHP in 2023.
• JavaScript: Rules the current web market. From W3Techs research, 98.7% of websites used JavaScript as of 2023.
• Java: Dominates the back-end development, especially for enterprise software. The big projects or company still uses Java for their back-end.

📌 Takeaway

• There are many languages out in the market, roughly 700-9000 languages in total.
• The translating language between the compiler and the machine code is called assembly language.
• PHP is still alive among the popular web development languages such as JavaScript or Python.
• Java is preferred in enterprise environments; hence, companies hire Java back-end developers.

💻 Solution

Questions

Q1) If we can use one programming language for web development, which language should we use?

My answer: JavaScript or Python Both languages can handle front/back end development by their own libraries and environment, such as Node.js or Next.js for JavaScript and Django for Python.

Q2) What is the best language that is easy to read and develop and has a huge library?

My answer: Python Python is recommended for the majority of beginner developers due to its easy syntax and also has a huge library from a huge community.

Q3) What is the benefit of having a good community for a programming language?

My answer: If the language has a good community, the users will develop more efficient and helpful libraries. More interest in the community will collect more users, and eventually, the community will create a virtuous cycle.

🔖 Review

• One programming language for web development: JavaScript
  • JavaScript is versatile and used for Full-stack development
  • It has a large ecosystem with a rich set of libraries and frameworks
• The best language for easy to read and develop: Python
  • Python is known for its clean and readable syntax
  • Ease of development and versatility are also the benefits of Python
• Having a strong community offers several benefits:
  • Support and collaboration
  • Knowledge sharing
  • Open-source contributions
  • Job opportunities
  • Tooling and ecosystem growth
