Delete element with specific value from array in typescript

Question

I have this:

  nominees: Array<{ id: number,  title: string, company: string, category: string }>;

I want to delete based on id, e.g. if the given id is 10, then I want to delete the element with the id of 10

I've been looking at splice, but honestly I'm really having a hard time. I'm quite new to Typescript

Well I honestly thought something like this would've worked this.nominees.splice(id);. Apparently it don't be like that. I'm looking for the similar function in java removeIf(...). Thought it was similar — Rigo Sarmiento

If you don't want to use splice, you can use filter as below:

let result = nominees.filter(n => n.id !== 10);

This would create a new Array, which may not be bad - but it could.

What about doing it in place ? nominees = nominees.filter(n => n.id !== 10);

Although it doesn't technically delete it, it gives me what I want. Thanks!

@Vincenzo Even then you would create a copy, which you afterwards assign to nominees . But as it seems this works for the thread opener.
