What is Angular 7?
Angular 7 is a JavaScript (actually a TypeScript based open-source full-stack web application) framework which makes you able to create reactive Single Page Applications (SPAs). Angular 7 is completely based on components. It consists of several components which forms a tree structure with parent and child components. Angular’s versions beyond 2+ are generally known as Angular only. The very first version Angular 1.0 is known as AngularJS.
“Angular is a complete rewrite of AngularJS by the same team that built AngularJS.”
What is Single Page Application (SPA)?
A single page application is a web application or a website which provides users a very fluid, reactive and fast experience similar to a desktop application. It contains menu, buttons and blocks on a single page and when a user clicks on any of them; it dynamically rewrites the current page rather than loading entire new pages from a server. That’s the reason behind its reactive fast speed.
Difference between AngularJS and Angular
| AngularJS | Angular |
|---|---|
| AngularJS is common and popular name of the first version of Angular1.0. | Angular is common and popular name of the Angular’s version beyond 2+ |
| AngularJS is a JavaScript-based open-source front-end web framework. | Angular is a TypeScript-based open-source full-stack web application framework. |
| AngularJS uses the concept of scope or controller. | Instead of scope and controller, Angular uses hierarchy of components as its primary architectural characteristic. |
| AngularJS has a simple syntax and used on HTML pages along with the source location. | Angular uses the different expression syntax. It uses “[ ]” for property binding, and “( )” for event binding. |
| AngularJS is a simple JavaScript file which is used with HTML pages and doesn’t support the features of a server-side programming language. | Angular uses of Microsoft’s TypeScript language, which provides Class-based Object Oriented Programming, Static Typing, Generics etc. which are the features of a server-side programming language. |
| AngularJS doesn’t support dynamic loading of the page. | Angular supports dynamic loading of the page. |
