[Fixed] Filter array of objects by array of ids

Issue

I have an array activeIds of ids of services and there is another array servicesList which contains objects of services.

Example: –

activeIds = [202, 204]
serviceList = [{  
                "id":201,
                "title":"a"
               },
               {  
                "id":202,
                "title":"a"
               },
               {  
                "id":203,
                "title":"c"
               },
               {  
                "id":204,
                "title":"d"
               },
               {  
                "id":205,
                "title":"e"
               }];

I want all the services(obj) whose ids are not a part of the first array i.e., activeIds. From the above example code I want service obj of ids 201,203,205

Final output –

expectedArray = [{  
                "id":201,
                "title":"a"
               },
               {  
                "id":203,
                "title":"c"
               },
               {  
                "id":205,
                "title":"e"
               }];

Here is my attempt to code. But it is not correct at all. Please help-

    const activeIds = e; // [202, 204]
    const obj = [];
    this.serviceList.map((s: IService) => {
        activeIds.map((id: number) => {
            if (id !== s.id) {
                obj.push(s);
            }
        });
    });

Solution

You can simply use array.filter with indexOf to check the matching element in the next array.

var arr = serviceList.filter(item => activeIds.indexOf(item.id) === -1);

DEMO

let activeIds = [202, 204]
let serviceList = [{  
                "id":201,
                "title":"a"
               },
               {  
                "id":202,
                "title":"a"
               },
               {  
                "id":203,
                "title":"c"
               },
               {  
                "id":204,
                "title":"d"
               },
               {  
                "id":205,
                "title":"e"
               }];


let  arr = serviceList.filter(function(item){
      return activeIds.indexOf(item.id) === -1;
    });
    
console.log(arr);
