TypeScript. FormGroup FormArray - remove only one element object by value. Angular 2 4

FormArray class has removeAt which takes the index. If you do not know the index, you can do a workaround:

this.images.removeAt(this.images.value.findIndex(image => image.id === 502))

In Angular Reactive Forms, formArray has a method called removeAt(). You can use it by passing an index that you want to delete:

delete(index){
    this.array.removeAt(index)
}
