Implement a feature that allows users to easily reset applied filters by clicking a button, but currently experiencing issues with the functionality

How to create an HTML button

<button
  id="styleButton"
  class="ml-2 refreshButton"
  (click)="removeAllFilters(appliedFilters)"
>
<i class="fas fa-sync-alt"></i>
</button>

JavaScript function for removing all filters

removeAllFilters() {
        this.appliedFilters = [];

        this.searchText = '';

        this.status.map(item => {
            if (item.name !== TypeStatus.ACTIVE) item.selected = false;
        });

        this.locations.map(item => (item.selected = false));

        this.roles.map(item => (item.selected = false));
    }

I attempted to implement the remove all filters function, but it is not functioning properly.

When using the map method, it is important to note that it does not alter the original array, but rather creates a new array with the desired modifications.

As a result, there are two options available to address this issue;

1. Replace map with forEach

removeAllFilters() {
        this.appliedFilters = [];
        this.searchStaffText = '';
        this.status.forEach(item => {
            if (item.name !== StaffTypeStatus.ACTIVE) item.selected = false;
        });
        this.locations.forEach(item => (item.selected = false));
        this.roles.forEach(item => (item.selected = false));
    }

2. Assign the modified arrays returned by the map method back to the original arrays.

removeAllFilters() {
        this.appliedFilters = [];
        this.searchStaffText = '';
        this.status = this.status.map(item => {
            if (item.name !== StaffTypeStatus.ACTIVE) item.selected = false;
            return item;
        });
        this.locations = this.locations.map(item => {
            item.selected = false;
            return item;
        });
        this.roles = this.roles.map(item => {
            item.selected = false;
            return item;
        });
    }

            return item;

    }

Initially, in your HTML file, you are invoking the function removeAllFilters(appliedFilters). However, it seems that the parameter appliedFilters is not defined in your TypeScript code.

Furthermore, there is an issue with how you are using the map method. Remember that every map function must have a return statement. Here is an example to illustrate this:

removeAllFilters() {
        this.appliedFilters = [];

        this.searchStaffText = '';

        this.status = this.status.map(item => {
            if (item.name !== StaffTypeStatus.ACTIVE) item.selected = false;
            return item; // MAKE SURE TO ADD A RETURN STATEMENT
        });

        this.location = this.locations.map(item => {
            item.selected = false;
            return item; // MAKE SURE TO ADD A RETURN STATEMENT
        });

        this.roles = this.roles.map(item => {
            item.selected = false;
            return item;
        });
    }
