Removing an element from an array of objects in Javascript

Question

Removing an element from an array of objects in Javascript

My situation involves an array containing objects:

var items = [{ id: 1, text: "test1" }, { id: 2, text: "test2" }, { id: 3, text: "test3"}];

In addition, I have this specific object:

var itemToRemove = { id: 2, text: "test2" };

My objective is to verify if the itemToRemove exists within the items array based on its id.

If it does exist, my goal is to remove it from the array:

  // pseudo code
  items.remove(itemToRemove);

Although I explored various javascript array methods, none seemed suitable for this task. Any help would be appreciated!

Answer №1

To exclude specific items from an array, consider using the filter method:

items.filter(function (item) {
    return item.id !== 2 || item.text !== "text2";
});

Avoid modifying the original array directly to maintain data integrity. Utilize the filter method to generate a new array without changing the original one.

To iterate through the array, use a simple loop and eliminate the matching element by utilizing splice():

for( let index=0; index<items.length; index++ ) {
  if( items[index].key == itemToDelete.key ) {
    items.splice( index, 1 );  // remove the specified item
    break; // exit the loop once the matching item is found
  }
}
