FindAndPopCollection

Usage:

const array = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday']

const collection = new FindAndRemoveCollection(array)

collection.findAndRemove(item => item === 'Tuesday') // Returns 'Tuesday'
// collection now has ['Monday', 'Wednesday', 'Thursday', 'Friday']

collection.findAndRemove(item => item === 'Tuesday') // Returns undefined

If you don't want to create a new class, you can always use it inline or anonymously:

const array = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday']

const collection = new (class FindAndPopCollection<T> {
  private _array: T[];

  constructor(_array: T[]) {
    this._array = _array.slice();
  }

  findAndRemove(predicate: (value: T) => boolean) {
    const index = this._array.findIndex(predicate);
    if (index !== -1) {
      const value = this._array[index];
      this._array.splice(index, 1);
      return value;
    }
  }
})(array);
