The most popular coding languages in the world

This article aims to leverage data from Statista for a review and comparative analysis of the leading programming language in the world today. At the end of this study, JavaScript emerged as the undisputed leader, with over 60% of developers using the language. 

The structure of this article is listed below.

  • A general overview of programming languages;
  • The Criteria for selecting a programming language;
  • Review of the ten leading programming languages worldwide.

Programming languages are tools that developers use to visualize, build and deploy various types of apps.  These languages differ extensively in their capabilities, functions, and development tools they provide. That is why some languages are more suitable for specific development projects.

The top backend providers in the world support popular languages for building web and mobile applications. However, a good knowledge of a language’s capabilities would help a developer select the most suitable specific development project.

Before we proceed to review the languages, let’s introduce programming languages to beginners. 

What are Coding Languages?

Programming language consists of various commands, instructions, and syntaxes for building apps on various computing platforms and embedded systems.

Programming languages are generally categorized into two, namely:

High-Level Programming Language: These are the set of languages used by developers to create various apps.

Low-Level Programming Language: The codes for an app must be converted to a low-level programming language before it works with the computing device hardware. 

The most striking difference between these two languages is that developers can read and analyze high-level programming language’s source code using familiar words and symbols.  For instance, such programming languages use terms such as “while.” “for,” “if,” “then,” and many others.  A few symbols used by high-level programming languages include “=.” +,” “<,” “{.”, and many more.  Many high-level programing languages are quite similar.

On the other hand, low-level programming languages consist of machine languages and assembly languages. Machine codes are also known as binary codes that the device processor can easily decode. They are utterly unreadable for humans. The assembly language has a complicated set of instructions and rules that make it challenging to read compared to the high-level programming language. 

A guide For Selecting a Coding Language for your Project

Since there are many programming languages in the world today, selecting the most appropriate one for your app project can be challenging. However, your business need and application requirement would determine the most appropriate programming language for any application. Here are the factors you should consider before selecting a programming language for any app development project.

  • Are developers with expertise in the technology readily available?
  • Is the platform opensource or proprietary?
  • Will the programming language be maintained on the long-term?
  • Your team’s ability to use the language effectively.
  • Alignment with development benchmarks and best practices.

The Top Ten Coding Languages

Selecting the right programming language goes a long way to enhance the success of an app development project.  Before we delve into the details, below is the summary of the top 10 programming languages’ features discussed in this article.

1. JavaScript

JavaScript allows developers to add dynamic content and effects to static web pages.  It can also create 2D and 3D animations, embedded media players, interactive maps, and many other active functions.  It is used along with HTML and CSS as the unofficial standard for creating web pages. 

The Advantages

 Client-Side Scripting language:  The code of JavaScript is executed by processors embedded within the browser. This feature reduces server loads because the code is no executed on the server. 

Easy Learning Curve:  Because the programming syntaxes are forgivable and straightforward, making it is easy to learn for new developers. Developers can leverage peer functions to create objects without hassles. So, creating codes to perform custom functions is less complicated with JavaScript.

Highly Responsive: JavaScript codes are executed fast, and the results/effects are displayed almost instantly. Therefore, the pages with dynamic content coded in JavaScript performs faster and uses fewer resources. Since all the processing is done outside the server environment, it helps conserve server transfer costs. 

Extends Web Pages Functions: It is packed with rich features that enhance websites with dynamic content, which are impossible to achieve with HTML and CSS.  IT has been used extensively to create carious functions, including visual effects, data processing, interactive web page functions, and many more.  JavaScript also makes it easy to embed third-party scripts into web pages.

Features of JavaScript

Works on Any Platform:  Since JavaScript is executed on the browser, it can work on all server architecture, operating systems, and computing devices. It can run on all of these platforms without the need to modify scripts.

It’s lightweight: JavaScript performs all its functions within the browser fast and uses minimal system resources. Unlike general-purpose programming languages, JavaScript requires few libraries. That is why it is a highly efficient client-side programming language used to create web apps. 

Dynamic Typing:  The dynamic typing feature of JavaScript allows developers to declare variables without specifying a data type.  Simply use the “var” keyword before a data type to convert it into a variable.

Object-Oriented Programming Language:  JavaScript supports the inheritance and encapsulation of object-oriented programming. This makes it easy to create reusable code-blocks. 

Coding Functions: JavaScript support the use of functions as a unique object type. This feature allows developers to inject functions into other functions and also use them as objects.

Prototype Feature:  Rather than use class inheritance, JavaScript uses prototypes. In essence, developers create classes and objects for every class. However, object prototypes in JavaScript must be defined to allow the creation of additional objects without conflict.  

2. HTML and CSS

HTML and CSS are the primary languages used in creating static web pages. While HTML creates the website structure, CSS is used for designing the layout to look great across different computing platforms.  These languages are great for scripting web pages and web apps.

Developers use CSS for creating customized appearance for various devices. It controls vital aspects of the web page, such as responsiveness to screen size, layout, colors, fonts, and other visual-related functions. CSS inherently works with HTML, but it can also be used with other XML-related markup languages.  Because the stylesheet is independent of the HTML content, it is reusable. CSS provides an excellent avenue for change website visuals, customize web-page for a specific platform. 

Benefits of CSS

Very Efficient: CSS allows the developer to code web pages efficiently by applying and modifying stylesheets.  After editing a single CSS file, the developer can use the change in thousands of web pages without lifting a finger, negating the need to edit pages individually.  A single piece of CSS code can modify the appearance of an entire website. 

Enhance Page Speed: Since CSS allows developers to pack fewer HTML codes in a web page, the website becomes lighter and loads faster. That is why CSS-based web pages load more quickly than other types of HTML pages. A fast-loading page offers users a better experience and ranks better in the search engine result pages. 

Easy to Maintain: CSS makes the procedure of updating and maintaining web pages more straightforward than ever before. Simply edit the CSS files to implement visual changes across the entire website. 

Features of CSS and HTML

  • A CSS rule contains two sections, which are the selector and detection components, respectively.
  • The selector component selects an HTML element to be styled.
  • Each declaration contains the CSS-property name, the value, and a semicolon.
  • Several declarations within a block are separated from one another with semicolons.
  • Each CSS block is enclosed in curly braces, while the semicolon indicates an end of a declaration.
  • A developer can use CSS selectors to locate an HTML element using parameters like name, attribute, class, id, and many more. 
  • Elements IDs are used for selecting unique elements. 
  • The # sign is used in an element attribute, so the ID can be called within CSS for styling. 
  • The period sign in front of an attribute indicates a class that can also be styled within CSS.
  • Class and ID universal selectors can be used to match any HTML element. 

3. SQL

SQL is the abbreviation for Structured Query Language, a programming language used to create and manage database connections.  In fact, it is the standard language for working with Relational Database Management Systems (RDBMS). Developers use SQL for various tasks ranging from creating databases to retrieving and updating database contents.

A few of the popular RDBMS are MySQL, Postgres, and Microsoft SQL Server. Most of these databases have their unique extension but depends on several SQL commands such as Create, Select, Update, Insert, and Drop for performing database-related operations.
