Making the transition from learning programming to becoming a developer can be challenging, but with the right approach, it is achievable. In this post, I will provide some guidance on how to navigate this journey. Start with a Course or Tutorial Begin your coding journey by taking a course or following tutorials. This can be in the form of video courses or YouTube tutorials. As you progress, start building simple applications and gradually move towards more complex ones....

Learn how to retrieve the result of an asynchronous function, whether it is promise-based or callback-based, using JavaScript. Imagine you encounter this scenario: you need to return the result of an asynchronous call from the original function. Here is a simplified example: const mainFunction = () => { const result = asynchronousFunction(); return result; } However, asynchronousFunction() performs an asynchronous operation, such as a fetch() call, and cannot directly return the result value....

One of the most popular libraries for working with Redis server in a Node.js application is node-redis, which can be found at https://github.com/NodeRedis/node-redis. To install the library in your project, run the following command: npm install redis Tip: If your project is brand new and does not have a package.json file, make sure to run npm init -y first. Connecting to the Redis Instance Once the library is installed, require it in your project using:...

The terminal is an essential tool for programmers, allowing you to perform tasks that would otherwise be impossible. Here’s a guide on how to use the terminal in macOS: Opening the Terminal: You can easily find the Terminal app by searching for “Terminal” in Spotlight or navigating to the Applications folder, opening the Utilities subfolder, and locating the Terminal app. Understanding the Shell: When you open the Terminal, you’ll see a screen similar to this: The “bash-3....

Having an extensive library of paper books has always been a passion of mine. Among them, programming books take up about 30% of my collection. I used to travel to the city to visit a well-stocked library, where I could find the best books on software development. Back in the day, when Linux was sold in 4 CD sets, books were the affordable way to learn programming independently. Aside from programming, a significant portion of my books revolves around self-improvement and personal growth....

Loops are an essential part of programming, allowing you to repeat a block of code multiple times. In Python, there are two types of loops: while loops and for loops. In this article, we will explore how to use these loops effectively in Python. While Loops While loops are defined using the while keyword and repeat their block of code until a certain condition is met. Here is an example of an infinite while loop:...

Enumerations are a fundamental concept in Swift that allows developers to group a set of different options under a common name. In this tutorial, we will explore the various features and capabilities of Swift enumerations. Creating Enumerations To create an enumeration in Swift, you define a new enum keyword followed by a name for the enumeration. For example, let’s create an Animal enumeration: enum Animal { case dog case cat case mouse case horse } In the above example, we have defined an Animal enum with four different cases: dog, cat, mouse, and horse....

Introduction Welcome to the Swift Objects tutorial, which is part of our Swift series. In Swift, everything is treated as an object, even basic values like numbers. This means that every value can receive messages and have associated functions called methods. Messages and Methods In Swift, each type can have multiple methods associated with it. For example, the number value 8 has a isMultiple method that can be called to check if it is a multiple of another number....

Optionals play a crucial role in Swift programming. They allow us to handle situations where a value may or may not be present. By declaring a type as optional, we indicate that it may contain a value or be absent. To declare an optional, we add a question mark (?) after its type. For example: var value: Int? = 10 In this case, value is not directly an Int but an optional that wraps an Int value....

The C preprocessor is a powerful tool that is indispensable when programming with C. It is an integral part of the C Standard, alongside the language itself, the compiler, and the standard library. The main purpose of the C preprocessor is to parse our program and ensure that the compiler has all the necessary information before proceeding with the compilation process. It performs various tasks to simplify the coding process and optimize the code....
