How can I start web development?

stp2y0 CommentsNewsbeginners, coding, community, development, engineering, help, inclusive, learning, software, webdev

Hello DEV community! TL;DR: I know how to code, but I want to learn web development, can you share tutorials? I'm making this post to ask how to make a website. I know it's an obvious thing to know for a lot of people, but I can't wrap my head at how web development works. In my job I work with NATURAL/ADABAS and I'm not expected to do modern things, but I want to start making freelance webs for friends. The only knowledge I have is HTML, CSS and JS. I made ""websites"" with them, but I know that these…

Sorting

stp2y0 CommentsNewsbeginners, coding, community, development, engineering, inclusive, java, learning, programming, software

Sorting algorithms are good examples for studying algorithm design and analysis. Sorting is a classic subject in computer science. There are three reasons to study sorting algorithms. First, sorting algorithms illustrate many creative approaches to problem solving, and these approaches can be applied to solve other problems. Second, sorting algorithms are good for practicing fundamental programming techniques using selection statements, loops, methods, and arrays. Third, sorting algorithms are excellent examples to demonstrate algorithm performance. The data to be sorted might be integers, doubles, characters, or objects. Section, Sorting Arrays, presented selection sort. The selection sort algorithm was extended to sort…

push() Method in JavaScript

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, javascript, learning, programming, software, webdev

The push() method in JavaScript adds one or more elements to the end of an array. This method modifies the original array and returns the new length of the array. Syntax : array.push(element1, element2, ..., elementN); Enter fullscreen mode Exit fullscreen mode *Example 1.: * const fruits = ["Apple", "Banana"]; fruits.push("Orange", "Mango"); console.log(fruits); // Output: ["Apple", "Banana", "Orange", "Mango"] Enter fullscreen mode Exit fullscreen mode *Example 2.: *How to Dynamically Add Elements Using the push() Method index.html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Fruit List</title> <link rel="stylesheet" href="https://dev.to/sudhanshu_developer/style.css"> </head> <body> <div id="container"> <h2>Fruit List</h2> <input…

Analyzing Algorithm Time Complexity

stp2y0 CommentsNewsbeginners, coding, community, development, engineering, inclusive, java, learning, programming, software

This section analyzes the complexity of several well-known algorithms: binary search, selection sort, and Tower of Hanoi. Analyzing Binary Search The binary search algorithm presented in BinarySearch.java, searches for a key in a sorted array. Each iteration in the algorithm contains a fixed number of operations, denoted by c. Let T(n) denote the time complexity for a binary search on a list of n elements. Without loss of generality, assume n is a power of 2 and k = logn. Since a binary search eliminates half of the input after two comparisons, Ignoring constants and nondominating terms, the complexity of…

Understanding the `this` Keyword in JavaScript

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, javascript, learning, programming, software, webdev

The this keyword in JavaScript can be one of the most confusing concepts for new developers. Its value can change depending on where it is used, making it crucial to understand its behavior in different contexts. This article will demystify the this keyword by exploring its use in various scenarios. What is this? In JavaScript, this refers to the context in which a function is executed. It provides a way to access properties and methods of an object from within the object itself. Global Context When used in the global context (outside of any function or object), this refers to…

AI Can’t Replace Teaching, but It Can Make It Better

stp2y0 CommentsAIalgorithms, artificial intelligence, education, learning, machine learning

Khanmigo doesn't answer student questions directly, but starts with questions of its own, such as asking whether the student has any ideas about how to find an answer. Then it guides them to a solution, step by step, with hints and encouragement.Notwithstanding Khan’s expansive vision of “amazing” personal tutors for every student on the planet, DiCerbo assigns Khanmigo a more limited teaching role. When students are working independently on a skill or concept but get hung up or caught in a cognitive rut, she says, “we want to help students get unstuck.”Some 100,000 students and teachers piloted Khanmigo this past…

Vector and Stack Classes

stp2y0 CommentsNewsbeginners, coding, community, development, engineering, inclusive, java, learning, programming, software

Vector is a subclass of AbstractList, and Stack is a subclass of Vector in the Java API. The Java Collections Framework was introduced in Java 2. Several data structures were supported earlier, among them the Vector and Stack classes. These classes were redesigned to fit into the Java Collections Framework, but all their old-style methods are retained forcompatibility. Vector is the same as ArrayList, except that it contains synchronized methods for accessing and modifying the vector. Synchronized methods can prevent data corruption when a vector is accessed and modified by two or more threads concurrently. For the many applications that…

I think the web is broken, or i am

stp2y0 CommentsNewscoding, community, development, engineering, frontend, inclusive, javascript, learning, software, webdev

Huhhm... (a sigh of lost hope) The world of a quiche eater isn't openly documented, well here is everything looming in my mind at-least just about howi think ui dev should be. Here is the backstory : I started my development journey by building android apps using DroidScript (a javascript framework), the issue is it's not cross-platform. NOTE : I refer to the native way of building ui. The native way looks something like this: function OnStart(){ let main = app.CreateLayout('linear','fillxy') let btn = app.AddButton(main, 'A simple Button', 0.8, -1) app.AddLayout(main) } Enter fullscreen mode Exit fullscreen mode I've gotten…
