What Are the Types of Coding Languages and Their Uses?

There are many types of programming languages. However, there are only a set amount of programming languages that we use regularly. This article will reveal the most popular types of programming languages, how many types of coding languages are there, and much more.

If you want to know the best coding languages for beginners and programming paradigms, this article will be very helpful. Any professional or aspiring programmer should know this information. Read below to learn more about the most popular programming languages and the type of programming language you should learn.

What Is a Coding Language? 

A coding language is also called a programming language, and it is used to create a bridge of communication between humans and computers. Coding languages are a set of commands to develop scripts, software programs, and other forms of instructions for computers to execute.

Computers receive instructions in binary, which is a language made up of ones and zeroes. Coding languages allow us to translate binary into what humans can interpret. Every time you use your computer to execute an action like running Google Chrome, coding languages communicate with your computer through binary to fulfill your request. 

How Many Programming Languages Are There? 

There are about 700 programming languages. However, there are around 250 popular languages. It’s tricky to estimate the exact amount of coding languages because new ones are created every year. Wikipedia has a comprehensive list of programming languages that can help you get a sense of what’s out there.

Although so many programming languages exist, there are only a few that are widely used. For example, most courses may only teach open-source or object-oriented languages as those are the most common among programmers. 

What Are the Types of Coding Languages and Their Uses?

Low-Level Coding Languages

A low-level language refers to code written in instructions that only the computer can understand. Humans can’t readily understand low-level coding languages. These coding languages are also heavily machine-dependent, and we don’t commonly use them today. 

It’s more likely for a professional programmer to work with low-level coding languages as they have complex syntax. Low-level code is also difficult to debug compared to high-level code. If you want to work with or learn machine learning, low-level code is ideal. 

The primary types of low-level code are assembly languages and machine code. Assembly languages are the gap between machine code and high-level coding languages. This type of low-level code uses abbreviations known as mnemonics. Mnemonics work with machine code to fulfill the programmer’s actions. This form of low-level code consists of binary code.

Advantages of Low-Level Coding Languages

  • The programs and software created by low-level coding languages function quickly and are memory efficient. 
  • A programmer can use a computer’s CPU and memory in optimized ways. 
  • Since you don’t need interpreters or a compiler to translate these types of coding languages, the interpretation time is decreased.

Disadvantages of Low-Level Coding Languages

  • Low-level coding languages are not suitable for beginner programmers as they are difficult to work with. 
  • Programs developed by low-level languages are more susceptible to errors. 
  • Developing, maintaining, and debugging low-level coding languages can decrease productivity compared to other language types. 

Middle-Level Coding Languages

We also call middle-level coding languages intermediate coding languages or pseudo-languages. These types of coding languages fill the gap between low-level and high-level coding languages. Middle-level coding languages interact with the abstract elements of a computer.

Most system and application programming languages are middle-level code. Middle-level coding languages are not as complex as low-level code, but there are similarities between the two. A common language associated with middle-level programming is C. 

Professionals use C programming to create systems that are part of larger operating systems like Windows. We use languages like C++ to develop games, browsers, and desktop apps because of how fast this language is. As a beginner programmer, knowing C++ is fundamental.

Advantages of Middle-Level Coding Languages

  • Middle-level code often produces machine code much faster than other levels of code. 
  • Coding languages that are middle-level have simple syntax.
  • Most middle-level codes are portable. 

Disadvantages of Middle-Level Coding Languages

  • There is little to no exception handling for middle-level coding languages. 
  • Middle-level code doesn’t support the concept of destructors and constructors. 
  • These types of programming languages don’t support run-time checking. 

High-Level Coding Languages 

Most developers and programmers use high-level coding languages. These types of coding languages are close to human language. Statements in high-level code derive from English. You don’t need to be proficient in computer hardware to utilize these languages because they don’t rely on particular machines. 

A high-level language is ideal for beginners, and this form of code is also very portable. To use high-level code, you need to interpret or compile it. High-level programming languages include Python, Ruby, Java, and PHP. 

The types of high-level code seem similar, but there are differences between each scripting language. You’ll find that some languages offer different speeds, functionality, convenience, and cross-platform support. The majority of in-person and online coding bootcamps teach high-level code. 

Advantages of High-Level Coding Languages

  • It’s easy to modify high-level code because the statements are in English. 
  • High-level code is portable. 
  • It’s faster to write and debug high-level code. 

Disadvantages of High-Level Coding Languages

  • The programs and software developed by high-level code don’t function as quickly as low-level code programs. 
  • High-level programs are less memory efficient than those developed with low-level code. 
  • High-level code does not communicate directly with the hardware. 

What Are the Types of Programming Paradigms?

The types of programming paradigms include functional, object-oriented, procedural, and logical programming. Below is a detailed explanation of each of these paradigms. 

  • Functional Programming. This type of programming paradigm describes software and programs that are developed by building functions. These functions are primarily mathematical. This paradigm is the opposite of object-oriented programming. 
  • Object-Oriented Programming. For object-oriented programming, objects are defined with their characteristics and methods. Instead of focusing on functions or logic like functional programming, you create software designs around objects and data. In this case, an object is a data field with unique behavior. 
  • Procedural Programming. New developers will learn this programming paradigm first. Procedural programming instructs a device on how to complete the requested tasks. This paradigm approaches data and operations as two separate concepts and follows a linear top-down method. 
  • Logical Programming. Logical programming relies on logic to describe rules and facts about a system. This paradigm tells devices what goal to accomplish instead of how to accomplish it. Each rule in logical programming has a head and body, and each fact only has a head.
