Modules<\/h4>\n<p>It is a place to group various units related to our application such as directives, components, services, etc.<\/p>\n<h4>2. Components<\/h4>\n<p>It is a typescript class in which you can create your properties, methods as per requirement and will bound with the HTML page to display the content to end user.<\/p>\n<h4>3. Templates<\/h4>\n<p>It is the user interface part of an angular application. A template is the HTML page which consists of the content that is being displayed at the user end.<\/p>\n<h4>4. Metadata<\/h4>\n<p>It is data about data. Decorators are metadata in angular.<\/p>\n<h4>5. Data Binding<\/h4>\n<p>It is the synchronization between data and DOM. There are two kinds of Data Binding in Angular 7:<\/p>\n<ul>\n<li>Event Binding<\/li>\n<li>Property Binding<\/li>\n<\/ul>\n<h4>6. Directive<\/h4>\n<p>Directives use for expanding the functionality of the HTML element. <em>Directives in Angular are Structural Directive, Attribute Directive, and Component Directive<\/em>.<\/p>\n<h4>7. Services<\/h4>\n<p>Services use to reuse the code. This service creates for that code which is common for more than one component.<\/p>\n<h4>8. Dependency Injection<\/h4>\n<p>It is an angular design pattern for enhancing efficiency and modularity.<\/p>\n<p>You will get to know more in detail about these features in another tutorial that focuses mainly on \u201c<strong>Architecture of Angular 7<\/strong>\u201d<\/p>\n<h2>Benefits of Angular 7 For Web Development<\/h2>\n<p>Multiple benefits come with angular 7 that invokes user to use it as a framework for their web developments.<\/p>\n<p><a href=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2019\/04\/Advantages-of-Angular-7.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-53606\" src=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2019\/04\/Advantages-of-Angular-7.jpg\" alt=\"Benefits of Angular 7 for web development\" width=\"1200\" height=\"628\" srcset=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2019\/04\/Advantages-of-Angular-7.jpg 1200w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2019\/04\/Advantages-of-Angular-7-150x79.jpg 150w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2019\/04\/Advantages-of-Angular-7-300x157.jpg 300w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2019\/04\/Advantages-of-Angular-7-768x402.jpg 768w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2019\/04\/Advantages-of-Angular-7-1024x536.jpg 1024w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2019\/04\/Advantages-of-Angular-7-520x272.jpg 520w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><\/a><\/p>\n<p>Some of the benefits of Angular 7 for web development are as follows:<\/p>\n<h4>1. Google Supported Community<\/h4>\n<p>Angular comes with <em>Google\u2019s Long-Term Support (LTS)<\/em>. The Google team is very optimistic about Angular\u2019s stability also many Google apps use an <a href=\"https:\/\/angular.io\/\">angular framework<\/a>.<\/p>\n<h4>2. Plain Old JavaScript Object (POJO)<\/h4>\n<p>It does not require any getter and setter function. Every object it uses is a plain old<a href=\"https:\/\/data-flair.training\/blogs\/javascript-objects\/\"><strong> javascript object<\/strong><\/a>. It provides javascript functionalities to enable manipulation of an object such as adding properties or removing properties from the object.<\/p>\n<h4>3. Declarative User Interface<\/h4>\n<p>Angular uses HTML to define the view part of an application which is a convoluted language. Html is a declarative language too. You don\u2019t need to worry about the flow of program when it loads just define what you want as per application requirement and angular will take care of rest things.<\/p>\n<h4>4. TypeScript<\/h4>\n<p>It is written in typescript, which is a superset of javascript. It promotes high security. If you have created proper map files during build time, then you can easily debug typescript code in an editor or on a browser.<\/p>\n<h4>5. Modular Structure<\/h4>\n<p>Angular organizes code into modules whether it is components, directives, pipes or services. It makes organizing of functionality easy and simple by separating the code. It also offers lazy loading, means loading of application feature in the background as per the demand of a user.<\/p>\n<h4>6. Consistency in Code<\/h4>\n<p>It improves the readability of code. For any new developer, it is an easy task to go through the project because of code consistency. It adds to their productivity too.<\/p>\n<h2>Why Choose Angular 7?<\/h2>\n<p>For career growth, one should be always ready to learn the latest technology and have good experience of it. If you are a web developer and looking for growth in career, you should have crystal clear knowledge of ANGULAR. The unique features of angular are the major reason for its popularity.<\/p>\n<p>There are two major reasons one look for while choosing a technology, One is the <strong>JOB OPPORTUNITY<\/strong> and second is the <strong>PAY SCALE<\/strong>.<\/p>\n<p><strong>Various Role of Angular JS Developer:<\/strong><\/p>\n<ul>\n<li>Web developer<\/li>\n<li>Web app developer<\/li>\n<li>Associate technology analyst<\/li>\n<li>UI developer<\/li>\n<li>UX developer<\/li>\n<li>Front-end developer<\/li>\n<li>JavaScript developer.<\/li>\n<\/ul>\n<p>And pay scale is decent for the angular developer as there is no other framework for web development is available in the current scenario as its competitor.
