Angular and AngularJS are two entirely different and unrelated frontend frameworks, although both are built by Google and have the same prefix in their name. AngularJS was released in 2010 and it was eventually replaced by Angular. Angular 7 is the latest version of Angular.
Angular 7 comes with powerful methods to easily build frontend applications. These features include support for two-way data binding, Angular Elements, CLI workspaces, Extended library support, Animation improvements, RxJS, etc.
Note: Very common Angular 7 interview questions.
