重复组成单词作为命名约定有什么意义？

Question

Let us say we have a component with this structure, why we need to repeat the word "component" in the naming of component's files, since we already have it in our parent folder? I saw that this is the recommended Angular 2 Style Guide . Maybe it is easier to tell that this file is about a component rather than a service, if you include it in the name, but other than that is there any other benefit?

components
    ├── edit-profile.component.ts
    ├── edit-profile.component.html
    ├── edit-profile.component.css

directives
    ├── form-validator.directive.ts
    ├── form-validator.directive.spec.ts
    ├── tooltip.directive.ts

services
    └── authorization.service.ts

That's what it is for.

If you create a feature than the related files should be kept together in a directory. To make them easy to distinguish when you have component(s), related directive(s), pipe(s), service(s) and maybe others in the same directory.

This is just a way of naming convension, nothing else. Keeping component as suffix in each file that belongs to a component is just to tell the developer that hey you, this file is related to a component named 'edit-profile' . file extensions are there to tell you that what kind of file it is for that particular component.

If you want to know that if this naming convention envolves in application building-compiling tasks, then NO, it doesn't .
