What is the difference between decorator syntax @Input('someValue') and @Input() in Angular 4?

I have not been clear what the difference between the two types of syntax is, thank you in advance

In addition to @Aravind post this is also the case for @Output and @ViewChild directives.

@Input() will not have any alias naming.

  • Example

     @Input() student:any[];
 <component [student]="...">

@Input('someValue') will take alias as someValue

  • Example

    @Input('studentInfo') student:any[];

<component [studentInfo]="...">

Explanation when you use alias make sure that you are using the alias in the HTML template.
