How to filter set of data based on current UserID in angular2

Hai i have a set of data, in that i must filter the data with my userId and display only that in the list. Please help. TS:

getDicomList() {
    this.service.getDicomList(params)
      .subscribe((res) => {
        this.dicomLists = res.Body.Data.dicomList;
        console.log(this.dicomLists, "shghds")
        let ids = this.dicomLists.map(item => item.CreatedBy);
       let filteredData = this.dicomLists.filter(item => ids.indexOf(item.CreatedBy) === -1);
      })

      i need to compare with my this.userId and item.CreatedBy

Console:

(10) [{…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}]

this.service.getDicomList(params)
  .subscribe((res) => {
    this.dicomLists = res.Body.Data.dicomList;
    console.log(this.dicomLists, "shghds")
    let ids = this.dicomLists.map(item => item.CreatedBy); // the map is used to filter the properties of the object if necessary
   let filteredData = this.dicomLists.filter(item => ids.indexOf(item.CreatedBy) === -1); // Filter YES but the criteria in the filter is not good
  })

JUST LIKE THAT

this.service.getDicomList(params).subscribe((res) => {
    this.dicomLists = res.Body.Data.dicomList;
    this.dicomLists.filter(item => item.CreatedBy === this.userId);
})

You should always place a null check

        getDicomList() {
        this.service.getDicomList(params)
          .subscribe((res) => {
                 this.dicomLists = [];
                 // Null check else it will throw errors
                 if(res.body && res.body.Data 
                      && res.body.Data.dicomList
                      && res.body.Data.dicomList.length){
                   this.dicomLists = res.Body.Data.dicomList;
                 }
           return this.dicomLists.filter(item => this.userId == item.CreatedBy);
          })

You just need small modification.

getDicomList() {
    this.service.getDicomList(params)
      .subscribe((res) => {
        this.dicomLists = res.Body.Data.dicomList;

       let filteredData = this.dicomLists.filter(item => item.CreatedBy === this.userId);
      })

Can you try below code

let filteredData = this.dicomLists.filter(item => (this.userId == item.CreatedBy));

Do like this,

getDicomList() {
    this.service.getDicomList(params)
      .subscribe((res) => {
        this.dicomLists = res.Body.Data.dicomList;
        console.log(this.dicomLists, "shghds")
        //let ids = this.dicomLists.map(item => item.CreatedBy);
       let filteredData = this.dicomLists.filter(item => this.userId == item.CreatedBy);
      })
