Filtering JSON array data in Typescript can help streamline and optimize data

Recently diving into Angular, I am facing a challenge with filtering data from a JSON array. My goal is to display names of items whose id is less than 100. The code snippet below, however, is not producing the desired result.

list : any;

getOptionList(){
this.callingService.getData().pipe(
  filter((l) => l.id < 100)
).subscribe(
  (l) => { this.list = l;} 
)
}
}

JSON Array retrieved from calling Service

[
  {
    "id":1,
    "name": "A"
  },
  {
    "id":2,
    "name": "B"
  },
  ...
]

Answer №1

this.serviceCaller.fetchData().subscribe((response: any) => {
      let filteredData = response.filter(entry => entry.id < 100);
      //You now have the filtered dataset.
});

This solution should be effective for your needs.
