If you're developing mobile or web applications, there’s a high probability that you’re working with APIs, more specifically REST APIs. Within that context, APIs allow developers to build today's mobile and web applications, which can implement significant features (e.g., user authentication, product information, payment processing, etc.) as well as provide a mechanism for application notifications. In this tutorial, we'll explore the key differences between REST and RESTful Types of APIs. We will provide examples as well as industry standards/best practices to illustrate what makes a REST API functionally important for building scalable applications. Understanding the REST API (with an example) A REST API (Representational State Transfer Application Programming Interface) is an interface (API) that enables communication between two separate applications via the internet, through the use of standard HTTP methods. At its core, a REST API allows one application to make a r...

When I started out as a web developer, I found that JSON was everywhere — APIs, React applications, projects using Node.js, and databases. I initially thought it would be difficult to be familiar with JSON, but once I got to know it, most things started to click. In this article, I will explain what JSON is, why it is used by developers, and how it fits into real-world usage in projects where JavaScript, React, or Node.js are being used. What is JSON? The abbreviation for JavaScript Object Notation is JSON; it is a lightweight file format that represents how different systems exchange and save information as a data format. To put it another way, JSON allows you to describe your data with text in the form of key-value pairs. Because JSON is designed for both humans and machines to read, it is easy for humans to read, and therefore very straightforward for machines to interpret and process. A Brief Comparison of JSON and XML: Although XML was once the standard data format for exchanging ...

If you're starting to explore the world of Web Development, JavaScript, React, or the MERN Stack, then knowing about both Git and GitHub is a must for your learning curve. Many new developers and programmers believe that GIT and GitHub both refer to the same application, however, they are both different applications. That's why I put together this simple guide on Git vs GitHub by providing real life examples that lend themselves to anyone who is just starting. What is Git? (Basics of Version Control System) The answer to the above question would be the version control system that developers use to manage their source code and keep track of the source code changes. In simple words,, Git will remember: The code that was created egg — the line of code that they wrote The changes made egg — the change you have made to the code since you created it Who made the change egg — who made the last change to your code When the change was made egg — the date and time that the last change wa...

  As mentioned earlier, modern applications rarely function in isolation. When I started looking into how an online shopping website and a weather application function, I became aware that every user action occurs through a series of interactions between various software components and systems. These interactions are typically made possible through the use of web services that act as a conduit for information sharing and communication between software applications and services. If you are new to web development, learning about web services can be a complex task; however, once you understand how they function, you will understand why the integration of web services is critical to developing fast, secure, and interoperable applications. In this guide, you will learn about web services, how they operate, their types, and their uses in the real world, and why they are essential to web developers. Understanding Web Service in Layman's Terms I often think of web services as a way of pro...

The human-readable code created using programming languages is translated into the machine language that computers understand. Two major tools are used to translate the source code: compilers and interpreters. It is important for novice programmers to understand the distinction between a compiler and an interpreter to write efficient, well-debugged code and begin a career in software development. In this document, you will gain an understanding of what compilers are, what interpreters are, their differences, benefits, examples, and beginner tips in layman's terms. What Are Compilers? A compiler is a software application that converts the entire source code into machine code and runs the program as a single output. Characteristics of Compilers: Compiles a whole program to produce one complete executable file Performs error compilation before executing the program Examples of Languages That Are Compiled: C/C++ Java (compiles into bytecode and is executed by the JVM) Benefits of Using...

JavaScript has played a crucial role as one of today’s most popular programming languages. It powers nearly all websites, web applications, and even a few servers. Therefore, by understanding how JavaScript has evolved over time, both beginner programmers and more experienced programmers can appreciate the current capabilities of this language and see why there is such a high demand for it in the software development community. 1. The Beginning of JavaScript Brendan Eich created the JavaScript programming language in 1995 while working for Netscape Communications Corporation in California. Originally called Mocha and live script, the programming language was ultimately named JavaScript. The purpose of JavaScript was to allow web authors to create interactive websites for users via their web browsers. The early version of this language was very simplistic and utilitarian; they were limited to filling out forms or creating clickable buttons to trigger some sort of action. 2. The Standard...
