Some people think that Angular is a short form of Angular JS but it is not at all. It is true that Angular JS & Angular both are used to develop front-end of application but both are not the same. In this blog we will understand Difference between Angular JS & Angular.
What is Angular ?
Angular is an open-source, cross-platform TypeScript based platform used to develop front-end(user interface) in web applications. It is completely re-created on AngularJS.ย Angular has OOP like features e.g. classes, datatypes, interfaces, inheritance, Lambda functions etcโฆas itโs a typescript based framework. To get idea about AngularJS please go through previous blog on Angular JS fundamentals.
What is TypeScript ?
TypeScript is an open-source scripting developed by Microsoft. It is a superset of JavaScript and has capability to run in both client & server side. Since Browser understands only JavaScript, every TypeScript code is converted to JavaScript code after transpilation (a kind of compilation which is called transpilation when we talk about typeScript). It is strongly typed language (datatypes), supports datatypes, classes, interfaces, inheritance,modules, Lambda functions etc.
What is the difference between Angular JS & Angular?
Basic Scripting
Angular is developed on top of TypeScript whereas AngularJS is developed on top of JavaScript.
Versionsย
Angular represents versions 2,4,5,6,7, 8, 9โฆโฆ.whereas AngularJS represents versions 1.x
Architecture
Angular uses Component & directives whereas AngularJS uses Model-View-Controller design.
Binding Syntaxย
Angular uses โ()โ for event binding & โ[ ]โ for property binding, whereas AngularJS uses โngโ directive to bind events & properties.
Mobile Supportย
Angular provides mobile support, whereas AngularJS doesnโt provide mobile support.
Dependency Injectionย
Angular uses dependency injection feature whereas AngularJS doesnโt use it.
Performanceย
Angular is better than AngularJS in performance especially for large-scale complex applications.
Features
Angular has more features & options in TypeScriptย as compared to AngularJS in JavaScript.
Upgrading code from Angular JS to Angular?
If you are upgrading from Angular 1 to Angular 2, there is a possibility that you have to rewrite the whole code as Angular 1 uses JavaScript whereas Angular 2 onward uses TypeScript. If you are into development of smaller web application, then better stick to Angular JS. In case you think it is essential for you to develop mobile apps, then better is to upgrade it into Angular. Hence, if possible, it is recommended to upgrade as soon as possible as migrating to a new version would require coding from the scratch.
