Best Programming Languages to Learn in 2022 (for Job & Future)
Table of Contents
One of the most important skills to learn in today’s world is to know how to write a computer program. Computers have entered almost every industry, whether that’s the autopilot in an aircraft or the digital speedometer in your bike.Today, almost every product and service makes use of computers in some way. So then, what are the best programming languages to learn?
Well, programming and developer communities are evolving at a faster rate than ever before. Several new programming languages and frameworks are popping up, suited for different categories of developers (beginners, intermediate, and experts) and for different use cases (web application, mobile applications, game development, distributed system, etc).
If you’re considering upping your skills and shifting into this highly sought-after domain, then you should know the different types and levels of programming, and of course what are the best coding languages to learn. That’s what we cover here.
The Levels of Programming
There exist several programming languages with their own specific purpose, with unique sets of keywords and syntaxes used to create instructions. Programming language vary in the level of abstraction and are classified into two categories:
- Low-level language
- High-level language
Low-level languages provide abstraction from the hardware and are represented in the binary form, i.e., 0 or 1 which are the machine instructions. Low-level languages are further classified as machine-level language and assembly level language.
Machine Level Language
Assembly Level Language
At the lowest level in the hierarchy and has zero abstraction from the hardware.
Above the machine level language in the hierarchy and has a little abstraction from the hardware.
Easier to learn and maintain.
Written in binary - 0s and 1s.
Written in simple English and is easy to understand.
A first-generation programming language.
A second-generation programming language.
Requirement for Translator/Assembler
The machine code is executed directly so no translator is required.
It requires an assembler to convert assembly language to machine code.
High-level language allows us to write programs that are independent of the type of computer. The high-level languages are named as high-level because they are closer to human language and can be understood easily, however it requires attention to the logic of the problem. The language needs a compiler to translate a high-level language into a low-level language. Further, the high-level languages provide the following advantage:
- Easy to learn and maintain
- Portable, i.e., they are machine-independent
Level of Understanding
Machine friendly; easily understood by computers.
User friendly; written in simple English.
Time of Execution
Takes time to execute.
Executes at a faster pace.
Requires the assembler to convert assembly code to machine code.
Requires the compiler to convert the high-level language to machine instructions.
NIt is not portable.
Not quite as memory efficient.
Debugging and Maintenance
Types of Programming
Before we move to popular coding languages, we should have a general understanding of the different types of programming languages. This is different from the levels of programming languages - programming language types refer to how the code is employed and designed, as opposed to where it sits on the machine-assembly-human hierarchy.
1. Procedural Programming Languages
The Procedural Programming Languages paradigm, derived from structured programming, specifies a series of well-structured procedures and steps to compose a program.
It provides a set of commands by segregating the program into variables, functions, statements & conditional operators. Some examples are Adobe Dreamweaver, Eclipse or Microsoft visual studio, BASIC, C, Java, PASCAL, and FORTRAN.
2. Functional Programming Languages
A functional programming language is a declarative programming paradigm where programs are constructed by applying and composing functions. The language emphasizes expressions and declarations primarily. The foundation of functional programming is lambda calculus which uses conditional expressions and recursion to perform the calculations. It does not support iteration like loop statements & conditional statements like if-else. Some of the most prominent functional programming languages are Haskell, SML, Scala, F#, ML, and Scheme.
3. Object-oriented programming Language
Object-oriented programming Languages are based on “objects” i.e. units that contain data in the form of fields and code in the form of procedures. OOP offers many features like abstraction, encapsulation, polymorphism, inheritance, and classes.
4. Scripting Programming Languages
All scripting languages are programming languages that do not require a compilation step. Rather, they are interpreted (there is no compile stage). The instructions are written for a run time environment. The languages are majorly used in web applications, System administration, games applications, and multimedia. It is used to create plugins and extensions for existing applications.
5. Logic Programming
The programming paradigm is largely based on formal logic. The language does not tell the machine how to do something but employs restrictions on what it must consider doing. PROLOG, ASAP(Answer Set programming), and Datalog are well known logic programming languages, with the rules written in the form of classes.
Now that you know that, we can finally move onto the top programming languages in 2022. These will serve you well if you intend to find a career in software development as they make up the majority of job opportunities.
Best Programming Languages
Python undoubtedly tops the list. It is commonly thought of as the best programming language to learn first because it is very approachable. It is a fast, easy-to-use, and easy-to-deploy programming language that is widely used to develop scalable web applications. YouTube, Instagram, Pinterest, SurveyMonkey are all built using Python.
The programming language provides a great starting point for beginners. If you’re looking for one of the more accessible and popular coding languages to learn, you should definitely try Python! A lot of startups use Python as their primary backend stack and thus this opens up a lot of opportunities for full-stack Python developers.
If you plan to get into the data science or AI industry, you will almost certainly have to learn Python. It can also be used in other fields, such as web development. The versatility and accessibility make it an excellent choice for beginners.
