How do I remove an array item in TypeScript?

Question

I have an array that I\'ve created in TypeScript and it has a property that I use as a key. If I have that key, how can I remove an item from it?

Answer 1

let departments is an array. You want to remove an item from this array.

departments: string[] = [];

 removeDepartment(name: string): void {
    this.departments = this.departments.filter(item => item != name);
  }

Answer 2

If array is type of objects, then the simplest way is

let foo_object // Item to remove
this.foo_objects = this.foo_objects.filter(obj => obj !== foo_object);
