I am currently working with an array and a load function that successfully loads all items in the array.
results: myArray[]
load() {
this.myService.getData().subscribe((response) => {
const searchModel = new SearchResultsModel(response);
this.results = searchModel.results;
});
}
Now, I want to retrieve a specific item from the array based on its id. To do this, I plan to replace this.results with
this.results = searchModel.results.find(x => x.id === 123456);
However, when attempting this change, I encountered the following error:
Type 'myArray' is missing the following properties from myArray[]: length, pop, push, concat and 28 others.
How can I resolve this issue?
_________ Update _________
After receiving advice on TypeScript from a colleague, I was able to make it work using the following approach:
import { find } from 'lodash';
this.results = [find(searchModel.results, { id: 123456 })];
The 'results' variable serves as the data source for a datagrid I am utilizing, which requires an array as input. Since the 'find' method returns an Object, I had to cast it into an Array.
