how to use ngrx entity selectors?

im using ngrx entity for my store the problem i cant select the store entities with selectors. i did as the code in this example https://github.com/angular-university/angular-ngrx-course/blob/master/src/app/courses/course.selectors.ts

in my situation when i use the select on the store i get the store object and not the entities.

this is my reducer:

this is the selectors:

this is the component:

this is the log from the select on the store, i expected a entities object and im getting this:

this is the store:

The is because the selector is wrapped inside a function.

const selectAll = () => createSelector(selectFoo, entities.selectAll);

Therefore you have to call the function, to get the selector's data instead of the store.

this.data = this.store.select(selectAll());

But my question is why the selector is wrapped, this isn't really needed. You can do:

const selectAll = createSelector(selectFoo, entities.selectAll);

And in your component you can use it like you're using right now:

this.data = this.store.select(selectAll);
