When we say a REST API is stateless, we mean: The server does not retain any information about previous requests (no session state).There is no stored “session” on the server that tracks who you are or what you were doing before. We can describe this better with an analogy. Analogy: Stateless vs. Stateful Using a …

In web development, we can unpack values from object properties to make our code cleaner and easier to work with. We assign these values to distinct variables, which we can now use further along our programming logic. Example: To make this ‘unpacking’ easier ES6 introduced a new feature called destructuring assignment. With destructuring, we can …

Superglobals are special built-in variables in PHP that are available from any function, class, or file without a previous declaration of them as global variables. That practically means there is no need to use the global keyword to access them. Below is how we can access a common global variable from a function: Without the …

We are going to construct a very simple MVC framework to get the concept. The code will be built and run locally with XAMPP. Those using Macs can use MAMP for the same purpose. Having a database and web server installed on your computer is the easiest and most affordable way to experiment with code. …

JavaScript provides three methods for declaring variables. We can use the var, let, and const keywords. This abundance of choices is a source of confusion for a beginner developer. At least it was for me. While taking my first steps in the world of JavaScript. I wondered, “Why should a programming language use so many …

MVC stands for Model-View-Controller, and it’s a way of structuring applications so they’re easier to understand, build, and maintain. A Brief History of MVC MVC isn’t new. It dates back to the 1970s, when a Norwegian computer scientist named Trygve Reenskaug introduced the concept while working at Xerox PARC. At the time, researchers were experimenting …

JavaScript is a dynamically typed — also known as untyped — language. Typing is the process of defining the data type of a variable. In dynamically typed languages, typing is associated with the variable’s value and not the variable itself. Thus, in JavaScript, variables don’t need to specify a certain data type when they are …

In programming, we instruct computers to do things, and we call these instructions programs. We can write programs using different programming languages, the same way we can communicate with other humans using different human languages. Each language consists of rules that dictate how to use data, and each data has a type. The operations that …
