Flutter.io Tutorials - Introduction & Setup

Image
Hello Friends, As Google launched flutter.io  for rapid cross-platform mobile app development. Let's start with some hands-on on it. What is flutter? It is an SDK, which supports cross-platform mobile app development that is same source code an compile and runs on Android and iOS as well. as flutter still in development (current version is 0.1.5),  It does not support 32 bit ARM devices. What differentiate from other cross-platform frameworks? Native OEM Native OEM is nothing but our native application framework like we write an android app in Java and iOS/iPhone apps in Objective-C. Native app creates widgets to communicate between widgets and platform services.   WebViews Initially, cross-platform app development is done using Javascript and WebViews like PhoneGap, jQuery Mobile, ionic etc. As you know (I hope) before Apple releases their iOS SDK they asked devs to use web apps to develop their app....

Object Oriented Programming in Javascript Tutorial

Object Oriented Javascript Tutorial Hello, All as the title suggest we are going to understand what is object-oriented in JS .  for those we don't have knowledge about Object Oriented Programming language, let's understand the terminology out OOP Language. OOP language is totally based on objects where the objects contain data, methods, and its attributes. let's take a realtime example as follows: I have fruits which are as follows as Banana, Orange, Lemon, Apple, Mango etc, so if I want to find a number of fruits I have then I can use length function to find out. The same way in  Javascript fruits  array is an object which has some properties and methods like  length is a property of array and sort is the method of an object. Nowadays, the Object-oriented Programming language is the more popular style for the programming language, and Javascript has taken the OOP concept from the scratch only. If we go d...

Solving LeetCode Problem 48: Rotate Image using JavaScript Welcome back, fellow coding enthusiasts! Today, we're going to dive into one of the interesting problems from LeetCode - Problem 48: Rotate Image . This problem challenges us to rotate an NxN 2D matrix (image) in place by 90 degrees clockwise. Let's explore the problem statement, understand the approach, and implement the solution using JavaScript. You are given an  n x n  2D  matrix  representing an image, rotate the image by  90  degrees (clockwise). You have to rotate the image  in-place , which means you have to modify the input 2D matrix directly.  DO NOT  allocate another 2D matrix and do the rotation.   Example 1: Input: matrix = [[1,2,3],[4,5,6],[7,8,9]] Output: [[7,4,1],[8,5,2],[9,6,3]] Example 2: Input: matrix = [[5,1,9,11],[2,4,8,10],[13,3,6,7],[15,14,12,16]] Output: [[15,13,2,5],[14,3,4,1],[12,6,8,9],[16,7,10,11]]   Constraints: n == matrix.length == matrix[i...
