You need to understand the entire process of creating a web application, from design and user experience to development and deployment. This means you need to be familiar with both front-end and back-end technologies.<\/p>\r\n<p style=\"text-align: justify;\">Most web developers will need to learn several different languages in order to create websites. There are many languages that programmers use to create web applications. The most common ones are HTML, CSS, JavaScript, and <a href=\"https:\/\/www.fita.in\/php-training\/\">PHP<\/a>. HTML is used for displaying information on a website and providing links to other pages. CSS is used for styling the appearance of web pages.<\/p>\r\n<p style=\"text-align: justify;\">JavaScript is a programming language that is commonly used for adding interactivity to a webpage. PHP is a server-side scripting language. It is used for writing programs that can be executed on a web server. All of these languages can be used together to create a website.

But there are some drawbacks to it. They cause extra load on the server because they must process requests twice. Also, redirects take longer to complete than static resources like CSS files or HTML documents.<\/li>\r\n \t<li><b>Avoiding duplicate codes<\/b> &#8211; Duplicate code refers to identical chunks of code being repeated across multiple pages. This causes additional load on the server because each request requires loading the same resource again. In addition, duplicate code increases the size of the file.<\/li>\r\n \t<li><b>Avoiding unnecessary images<\/b> &#8211; Images are great for adding visual interest to webpages. However, large images require more bandwidth and storage space than smaller ones. If you don&#8217;t need an image, consider using a tool like TinyPNG to reduce the size without losing quality.<\/li>\r\n \t<li><b>Leveraging browser caching<\/b> &#8211; Browser caching allows us to store frequently accessed resources locally rather than fetching them every time a visitor visits our website. This reduces the amount of data we need to serve to visitors and improves overall speed.<\/li>\r\n \t<li><b>Deferring parsing of Javascript<\/b> &#8211; When a webpage loads, it parses the HTML document into individual elements and creates DOM objects. These objects allow us to access information about the structure of the page and interact with the page. For example, we might want to change the color of certain parts of the page. To do this, we&#8217;d need to find those parts of the document and manipulate them individually. Instead, we could defer the parsing of the document until later.

What is the difference between AMD and CommonJS?<\/a><\/h4>\r\n<\/div>\r\n<div id=\"collapse32\" class=\"content panel-collapse collapse\">\r\n<div class=\"panel-body\">\r\n<p style=\"text-align: justify;\">In my opinion, most would agree that both are ways to implement a modular architecture. However, there are some key differences between the two approaches. Let\u2019s take a look at what makes each approach unique and why it might be better suited for certain situations.<\/p>\r\n<p style=\"text-align: justify;\"><strong>CommonJS- <\/strong>The CommonJS specification defines a way to organize your code into separate files and load them together into a single application. This allows you to reuse common functionality across multiple applications without having to rewrite everything again and again. You can use CommonJS to build single-page apps, web servers, desktop applications, mobile applications, etc.<\/p>\r\n<p style=\"text-align: justify;\"><strong>AMD- <\/strong>AMD is a specification for defining how to load JavaScript modules. Its goal is to make sure that modules loaded in different parts of an application don\u2019t interfere with each other. For example, if you want to load jQuery once in the browser and another version of jQuery in your server-side code, you can do that easily with AMD.<\/p>\r\n<p style=\"text-align: justify;\"><b>So, which approach is best for me?<\/b><\/p>\r\n<p style=\"text-align: justify;\">That depends on your situation. If you\u2019re building a single-page app, you probably won\u2019t need to worry about the difference between CommonJS and AMD. But if you plan to deploy your application to a server, you\u2019ll definitely want to use AMD.<\/p>\r\n\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<div class=\"panel panel-default1 set\" style=\"text-align: justify;\">\r\n<div class=\"panel-heading1\">\r\n<h4 class=\"panel-title\"><a href=\"#collapse33\" data-toggle=\"collapse\" data-parent=\"#accordion\"><i class=\"more-less1 fa fa-plus a-less\"><\/i><i class=\"more-less1 fa fa-minus l-less\"><\/i><span class=\"q-num\">Q33<\/span>.

This slang term describes a situation where there are multiple asynchronous functions dependent on each other. These functions depend on one another so it gets very messy with so many callbacks nestled within so many layers. You end up having code that is difficult to understand and maintain, and looking like a pyramid as shown above.<\/p>\r\n<p style=\"text-align: justify;\">This is because it is hard to see the flow of the application and debug issues.

What do you mean by MEAN Stack?<\/a><\/h4>\r\n<\/div>\r\n<div id=\"collapse85\" class=\"content panel-collapse collapse\">\r\n<div class=\"panel-body\">\r\n<p style=\"text-align: justify;\">There are four technologies in the MEAN stack \u2013 MongoDB, ExpressJS framework, AngularJS, and node.js \u2013 used to develop web applications. Developed by MongoDB founder Eliot Horowitz, it is best suited for prototyping, rapid development, and small projects. It is an ideal solution because it is easy to use and requires no server configuration.<\/p>\r\n<p style=\"text-align: justify;\">MEAN stack is a popular choice among developers because it allows them to build fast and scalable web apps without having to learn complicated frameworks like Ruby on Rails or PHP. This makes it easier to build robust web applications.<\/p>\r\n\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<div class=\"panel panel-default1 set\" style=\"text-align: justify;\">\r\n<div class=\"panel-heading1\">\r\n<h4 class=\"panel-title\"><a href=\"#collapse86\" data-toggle=\"collapse\" data-parent=\"#accordion\"><i class=\"more-less1 fa fa-plus a-less\"><\/i><i class=\"more-less1 fa fa-minus l-less\"><\/i><span class=\"q-num\">Q86<\/span>. In ES6, what do you mean by Temporal Dead Zone?<\/a><\/h4>\r\n<\/div>\r\n<div id=\"collapse86\" class=\"content panel-collapse collapse\">\r\n<div class=\"panel-body\">\r\n<p style=\"text-align: justify;\">Before ES6, variable declarations had to use one of three keywords: var, let, or const. These keywords define the scope of the variable, which determines where it can be used. For example, In JavaScript, global variables such as x can be referenced anywhere, whereas local variables are defined within functions.<\/p>\r\n<p style=\"text-align: justify;\">With ES6, there are now two additional ways to declare variables: let and const. Let and const both introduce a new concept called block scoping. Block scoping allows us to specify what types of variables can be declared in different places. In particular, let and const are block-scoped; this means that they can only be accessed inside the curly braces ({}) that surround them. This makes them behave differently from regular variables.<\/p>\r\n<p style=\"text-align: justify;\">Let and const don&#8217;t have temporal dead zones, meaning that they can be accessed before being assigned values. However, unlike normal variables, let and const aren&#8217;t hoisted to the top of the containing scope. Instead, they must be explicitly declared.<\/p>\r\n\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<div class=\"panel panel-default1 set\" style=\"text-align: justify;\">\r\n<div class=\"panel-heading1\">\r\n<h4 class=\"panel-title\"><a href=\"#collapse87\" data-toggle=\"collapse\" data-parent=\"#accordion\"><i class=\"more-less1 fa fa-plus a-less\"><\/i><i class=\"more-less1 fa fa-minus l-less\"><\/i><span class=\"q-num\">Q87<\/span>.

Event capturing happens when an event propagates down the DOM tree instead of up. An event handler attached to an ancestor element will receive notification about the event. If the event handler does nothing with the event, then the event will bubble back up the DOM tree to the event source.<\/p>\r\n\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<div class=\"panel panel-default1 set\" style=\"text-align: justify;\">\r\n<div class=\"panel-heading1\">\r\n<h4 class=\"panel-title\"><a href=\"#collapse89\" data-toggle=\"collapse\" data-parent=\"#accordion\"><i class=\"more-less1 fa fa-plus a-less\"><\/i><i class=\"more-less1 fa fa-minus l-less\"><\/i><span class=\"q-num\">Q89<\/span>.
