This thread will be talking about `promises` and this is a continuation of the async functions post. Click on this link "https://afr.ng/8cf2385e" if you haven't read the async/await post.So JavaScript is all about keeping things moving, but sometimes you have got to wait for something to finish. Promises are here to ensure you don't get stuck in code limbo!**What are Promises?**Promises are objects that represent the eventual completion (or failure) of an asynchronous operation. They act like a placeholder, saying "Hey, I'll get you the result when it's done."**Think of it like an order:** Ima...

JavaScript thrives on making things happen, but waiting for slow tasks can bring your app to a screeching halt. Enter async/await, a powerful duo that simplifies asynchronous programming with a touch of magic.**Async and Await: A Perfect Match*** **Async Functions:** Imagine a function fetching data. A regular function would block everything until the data arrives. An `async` function, however, returns a Promise immediately, allowing your program to keep running.

Hello, Africoders! 🌍Our story begins in the late 1980s with a Dutch programmer named Guido van Rossum. Guido was working at Centrum Wiskunde & Informatica (CWI) in the Netherlands. During the Christmas holidays of 1989, he decided to work on a new project to keep himself occupied. Little did he know, he was about to create something that would revolutionize the programming world.### Why Python?Guido wanted to develop a language that was easy to read and write, but also powerful enough for various tasks. He was inspired by ABC, a teaching language he had worked on before, and aimed...

Hello, Africoders! 🌍We've all faced the stress of looming deadlines and felt overwhelmed. Juggling multiple tasks, ensuring the code is bug-free, and meeting the deadline can push anyone to their limits.I was working on a web application project for a client with a tight deadline. The night before the launch, I found myself debugging a stubborn piece of code related to user authentication that just wouldn’t cooperate. Every time I tried to log in, I encountered errors, and I could feel the pressure mounting.As the clock ticked, I knew I had to act quickly. Prioritization became my best...

Hey Africoders!This semester, my study group and I explored the intricacies of cryptography, focusing on cipher blocks – the building blocks of many encryption algorithms. I'm excited to share some insights we gained!**Cipher Blocks: Segmenting Data for Secure Transmission**At its core, a cipher block is a deterministic algorithm that processes fixed-length groups of bits, known as plaintext blocks. Imagine you have a large text file to encrypt; a cipher block divides this file into chunks of a specific size, akin to how a computer program segments a large array into smaller sub-arrays for eff...

Hey, Africoders!Did you know the very first computer programmer, the one who wrote the first program, was actually a woman? Her name was **Ada Lovelace**, and while she may not have coded on a modern computer, her work in the mid-1800s laid the groundwork for the entire field of computer programming!Ada Lovelace worked with Charles Babbage on his ambitious Analytical Engine, a machine designed to perform complex mathematical calculations. Though the machine itself was never fully built, Ada, in her notes, theorized about its potential and wrote instructions (the first computer program!) for...

Hello, Africoders! &#127757;Ken’s first task was to submit code for review. he felt a mix of excitement and nervousness. Just like Ken, many of us face similar feelings. How do we navigate this process smoothly?---### Best Practices for Giving Feedback1. Be Constructive: Ken's colleague, David, reviewed he code. Instead of pointing out mistakes harshly, he provided constructive feedback. "I noticed this function is a bit complex. Perhaps we can break it down into smaller, more manageable parts?" How do you provide constructive feedback?2. Be Specific: David was specific in his feedback. He poi...

Hello, Africoders! &#127757;The first time I truly understood the power of keeping my code DRY was during a late-night coding session. I found myself repeatedly copying and pasting blocks of code to handle a common task across different modules of my application. It was tedious, error-prone, and frankly, exhausting.DRY, or “Don't Repeat Yourself,” isn’t just a coding principle; it’s a mindset shift that promotes efficiency and clarity in software development. Imagine this scenario in a healthcare setting: managing patient appointments. Every time a patient schedules an appointment, the logic b...
