What is Coding

  • A computer program's source code must be written, tested, implemented, and maintained. The code is written in a programming language, which has its own syntax and meaning. If you want to be able to code, you need to understand this language and how it works. 
  • Coding plays a vital role in computer systems. The majority of electronic devices that you use rely on code. While it seems complicated at first, if you break it down, it's quite simple.
  • Coding is essential to building computer programs, apps, and websites. Every website, every browser, every operating system, every app on your phone, and even Facebook is made from coding. 
  • Those who write code are called programmers, coders, or developers. Their job is to create apps, websites, and games using a computer.
  • In coding, instructions are created for computers using a programming language. Almost every website, app, and other technology we use today was developed using computer code. 
  • Communication with computers is done through coding. Code allows computers and other machines to be instructed on how to perform certain actions. In simple words, if you go to a new place where you don’t know the native language, You can use English to communicate with people as English is a universal language.
  • Here computer does not understand the English language so humans have created several programming languages to tell the computer what it has to do. So this process is called coding.

What is a Program

  • In computing, a program is a specific set of ordered operations for a computer to perform. A program is a piece of software that runs on a computer. It is similar to a script, except it is often much larger and does not require a scripting engine to run. Instead, a program consists of compiled code that can be run directly from the computer's operating system.

  • A program is written in some kind of computer language. The source program consists of your language statements. Then you compile the source program (using a special program called a language compiler) to create an object program (not to be confused with object-oriented programming). Compiled programs and object programs are synonyms for object programs. A logic processor interprets string representations of 0s and 1s as object programs.

What is a Programming Language

Programming languages are a vocabulary and set of grammatical rules that instruct a computer or computing device how to perform specific tasks. A software program is a set of instructions, commands, and syntax.

Programming languages are notations for connecting instructions to machines or computers. Typically, programming languages are used to control the performance of a machine or to express algorithms. Programming languages are currently used in thousands. Many computer languages should be written in the imperative form, while others should be written in declarative form. Syntax and semantics are two kinds of programs. 

The term programming language refers to high-level languages such as BASIC, C, C++, COBOL, Java, FORTRAN, Ada, and Pascal.

Types of Programming Language

Programming languages can be divided into three categories:

  • Machine language.
  • Assembly language.
  • High-level language.

What are High-Level and Low-Level Languages

A high-level language is much understandable and closer to human beings. These are the instructions given by a programmer to a computer. The computer understands only low-level language which consists of 0’s and 1’s. So a compiler is used which translates a high-level language to a low-level language. Then the code is executed.

Machine language is composed of bit patterns that are directly executed by a computer, whereas Assembly language is a low-level language that requires a compiler and interpreter to be converted to machine language. 

Assembly languages are designed to be readable by humans, unlike machine languages, which contain binary and hexadecimal characters. The Assembly language sits between the high-level language and machine language.

What is a Procedural Programming Language

Programming in procedural languages may be the first paradigm a new developer learns. A procedural code is, at its core, the information that specifies how a device should perform a given task. According to this paradigm, data and procedures are two different entities and are treated as separate. The concept of Procedural Programming divides the program into procedures, which are also known as routines or functions, and simply contain a series of steps to be carried out.
To put it simply, Procedural Programming involves writing down a list of instructions that tell the computer what it must do step-by-step to complete the task at hand. Procedural languages include BASIC, Pascal, and C.

What is an Object-Oriented Programming Language

The Object-Oriented Programming paradigm (OOP) uses classes and objects as its building blocks. A software program is structured into simple, reusable blueprints of code (called classes), which are then used to create individual instances of objects. JavaScript, C++, Java, and Python are all object-oriented programming languages.

What is a Functional Programming Language

Functional programming (also called FP) is a way to think about software construction by creating pure functions. In contrast to Object-Oriented Programming, it avoids the concept of shared state and mutable data.

Expressions and declarations are more important than statements in functional languages. A list of some popular functional programming languages follows:

  • Haskell
  • SML
  • Clojure
  • Scala
  • XSLT
  • SQL
  • Mathematica

What Makes a Programming Language Unique?

Even though many programming languages are relatively simple, they perform different tasks. Web pages and front-end development are the primary uses of JavaScript, one of the most popular languages. Python, on the other hand, can be used for both complete software programs and websites.

A programmer can often use more than one programming language for the same purpose, so whichever he or she chooses is usually up to discretion.

What is Front-End Coding Language

Front-end languages are programming languages used by developers to build a website's front end. Visitors see the external end of the site through this 'front end'. Front end languages differ, so the web developer's role would be to create a theme in line with the site's style. Before visitors see the intended content, these languages are installed on the site. 

In computing, the front end is the graphical user interface that simplifies the process of using a computer. MS-DOS 3.11 was an interface for the command line in Windows 3.11. Prior to Windows, the user had to memorize a series of commands to perform tasks on the command line, which made computers difficult for most users.

The widely recognized front-end languages are JavaScript, CSS, React, and HTML.

What is Back-End Coding Language

In web applications, backend development languages handle the 'behind-the-scenes' functionality. The code connects the web to a database, manages user connections, and powers the web application itself. The backend works in conjunction with the front end to deliver the end product to the end-user.

Write APIs, write code that interacts with databases, create libraries, work on business processes, and much more are some of the responsibilities of backend programmers. Often, it depends on the role and company. 

Object-oriented programming (OOP) and functional programming are both possible backend programming approaches.Examples of Backend Programming Languages:

  • Java
  • PHP
  • .NET (C#, VB)
  • C#
  • VB
  • Ruby
  • Python
  • SQL
  • JavaScript

Uses of Coding

We've seen rapid technological advancements over the last few decades that have altered the way everything works. You have to look beneath the surface to see where the most significant changes occurred. Millions of working hours and warehouses of analog machines were replaced with faster, safer, and more reliable computers.

You can find code anywhere since computers run on code. In everything from microwaves to power plants, computers will continue to replace outdated technology. Consequently, we will be exposed to more code every day.

Almost every aspect of modern life relies on coding, even though computer science deals with high-level theoretical ideas. The technologies used to run applications on phones, tablets, and computers are computer languages. 

In addition to smart TVs, calculators and other digital systems use it. In virtually every new car, it controls everything from the air conditioning to the fuel injectors. Several cities use computers to operate traffic signals.

Analog systems are now streamlined by using computerized systems. A more efficient structure, machine, and system are the result of this technology. Coding is also used in some of the most advanced technical fields (such as artificial intelligence and machine learning). Some industries highlighted include:

  • Healthcare
  • Financial Trading
  • Aviation
  • Data Journalism
  • Industrial Manufacturing
  • Art
  • Music
  • Geophysics
  • UX Design
  • Social Media
  • Basketball
  • Web Development
  • Digital Cartography
  • Speech Therapy

Important Of Coding 

  • Coding affects more than just your everyday life. Whenever you leave your home, you are engaging with programming unknowingly. In today's world, programming is everywhere and you encounter it on the street, at your workplace, and the grocery store. Whether you're using a word processor to create a letter or an email platform to send messages, you encounterbar-code scanners regularly, and you almost certainly use a lot of code while working
  • Your car has a bunch of computers controlling everything from fuel, oil, and power management to cruise control and navigation. Additionally, the highway system's computer code is poor. Nowadays, most traffic lights are little computers, and city-wide traffic networks are also controlled by computers. Even elevators before controlled by processors and sent to the correct floors with code can't escape it.

Perhaps you have wandered from time to time why you should be concerned with coding since your position as a rodeo clown requires very little computer assistance. You should understand how crucial coding is to every aspect of modern life, and you'll gain a new appreciation for how it's changed our world. 

  • Coding is a basic literacy in the digital age, and kids need to be able to understand and be able to work with and understand technology. Children who learn coding at a young age are better prepared for the future.  In addition to improving communication skills and creativity, coding enables children to gain confidence and math skills. Understanding computers and learning the basics of coding help children to develop an understanding of how things work. Additionally, it teaches them how software engineers solve problems logically and creatively using math. Children should learn these skills while they are young, so schools should teach coding.

In general, solving problems is considered to be a valuable life skill. In order for our children to succeed in life, we want them to be excellent problem solvers. While children are young, learning how to code can help them develop this kind of skill and help them later in life. One of the biggest reasons to learn coding is for this reason. 

  • Coding requires children to take a vague idea and turn it into something useful. When the first solution doesn't work, they try another. It won't work, so they try again until it does. Computational thinking is highly valued by employers, as this style of thinking is developed through coding. 
  • Coding is an extremely useful skill to have when you consider how the world is developing. Not just technology-related businesses rely increasingly on computer code.

Children who learn how to code will have an advantage in life with more employment opportunities in the future regardless of the industry they choose to enter, whether it is in the technology sector, finance, retail, health, etc. The importance of coding in schools cannot be overstated.

  • Coding helps with more than just programming roles. Programming enhances analytical skills, language proficiency, attention to detail, and discipline. Almost any career can benefit from these. We will increasingly need people proficient in coding as digital technology becomes more prevalent in our daily lives.
