What is the most effective way to compare two arrays of objects in JavaScript?

I'm working on a function that needs to return an array of elements based on certain filters. Here is the code for the function:

filter_getCustomFilterItems(filterNameToSearch: string, appliedFilters: Array<any>) {
   let tempFilterArray = [];
   let masterFilterList = getMasterFilterList();
  
   // More details about the variables used in the function
  
   for (let masterFilterItem of masterFilterList) {
     // Missing logic section
   }
}

I need to filter the masterFilterList to get an array of items where filterNameToSearch = 'Item2' under specific conditions:

1) For each element in appliedFilters, compare appliedFilterItem.name with

masterFilterItem[appliedFilterItem.name]
and check if any of the filters in appliedFilterItem have the same value as
masterFilterItem[appliedFilterItem.name]

2) The condition should resemble something like

masterFilterItem[appliedFilterItem[0].name] == appliedFilterItem[0].filters[0].value && appliedFilterItem[0].filters[0].status === 'selected' && masterFilterItem[appliedFilterItem[1].name] == appliedFilterItem[1].filters[0].value && appliedFilterItem[1].filters[0].status === 'selected' and so on for all appliedFilterItems
. The number of elements in appliedFilters is dynamic.

If anyone could assist me with this problem, it would be greatly appreciated.

Answer №1

  in a given masterFilterList, return filtered elements based on the filterNameToSearch value from appliedFilters
      .filter(value => 
         check if any appliedFilters match the filterNameToSearch value and have filters with status "selected" and matching value
         (
            name === filterNameToSearch &&
            filters.some(filter => 
              filter.status === "selected" &&
              filter.value === value
            )
         )
      );
