High-level, interpreted programming language. It is a language which is also characterized as dynamic, weakly typed, prototype-based and multi-paradigm
Have you heard about memoization? It's a super simple thing, by the way,– just memoize which result you have got from a first function call, and use it instead of calling it the second time - don't call real stuff without reason, don't waste your time.
Skipping some intensive operations is a very common optimization technique. Every time you might not do something — don’t do it. Try to use cache — memcache, file cache, local cache — any cache! A must-have for backend systems and a crucial part of any backend system of past and present.
In my work, I often encounter various services designed to simplify tasks across different areas. I’m not talking about tools like GSA or A-Parser but about Zennoposter or BAS. I am no professor in automation, so I’ll explain in layman's terms: these services are essentially complex, multi-layered platforms that allow the creation of bots and scripts to perform almost any task without human intervention—a sort of “basic neural network.” By the way, such services existed long before neural networks became mainstream for everyday use.
While exploring BAS, I encountered a situation where many developers creating BAS scripts (ironically, developers developing) idealize CAPTCHA solving using clicks.
Do you want to know how to build an AI image analyzer? Then read this article till the end! I'm going to show you how to build AI analyzer tools really simply, so you almost don't have to have any prior knowledge. I will take you step by step, and we will use Project IDX and the Gemini API. This means you don't have to set up anything; everything we will do is on the cloud. If you're ready, then let's get started!
The new code as the side effect
If we use the reducer function for form data handling It has an infinite list of returned values, which expands when the next development iteration updates the interface defining the form and implements a new field. So the reducer pattern is procedure code, not a functional
If you’re a React developer, you know how important state management is. State is the data that powers your UI, making it interactive and dynamic. But managing state in React can be tricky, especially when you have to share it across multiple components or deal with complex and asynchronous logic.
That’s why over the years, React developers have come up with various solutions for state management, each with its own advantages and disadvantages. In this article, we’ll take a look at some of the most popular ones and how they evolved. We’ll also review some of the current state-management libraries and how to choose the best one for your app.
Hello, fellow front-end developers! Imagine a tool that’s not about punching in commands but a gateway to a world of coding artistry. That’s what the macOS Terminal became for me at Luxoft.
In the realm of frontend development, the quest for enhancing user interaction remains a constant pursuit. Developers, inspired by innovation, often seek solutions to refine components for a seamless user experience. Today, we delve into the construction of an advanced dropdown component using Svelte — a framework known for its simplicity and effectiveness.
Hello, dear users of the IT world!
In modern web development there are many ways to make your website interesting and attractive to users. And even using simple techniques you can achieve great results!
I suggest you to create a mini-game from scratch yourself. And then, you can use it to liven up and add interactivity to any web page.
This custom hook is particularly beneficial in scenarios where you need to handle user input, such as search bars or form fields, where you want to delay the execution of an action until the user has finished typing or interacting. It's also useful for optimizing network requests, ensuring that requests are sent only after the user has stopped typing or selecting options.
In the first part of You don't know Redis, I built an app using Redis as a primary database. For most people, it might sound unusual simply because the key-value data structure seems suboptimal for handling complex data models.
In practice, the choice of a database often depends on the application’s data-access patterns as well as the current and possible future requirements.
Redis was a perfect database for a Q&A board. I described how I took advantage of sorted sets and hashes data types to build features efficiently with less code.
Now I need to extend the Q&A board with registration/login functionality.
I will use Redis again. There are two reasons for that.
Firstly, I want to avoid the extra complexity that comes with adding yet another database.
Secondly, based on the requirements that I have, Redis is suitable for the task.
Important to note, that user registration and login is not always about only email and password handling. Users may have a lot of relations with other data which can grow complex over time.
Despite Redis being suitable for my task, it may not be a good choice for other projects.
Always define what data structure you need now and may need in the future to pick the right database.
