JSON – delete filtered item from parent object

I have a JSON object (although for this example I am going to hard-code it into the example) and I would like to delete an item based on its key item. I do not want to use the delete [index] method.

How could I filter my list to get the key-value pair I would like to remove, and then delete that entry only.

I have tried the below but it doesn’t work.

(I am using Javascript)

Thanks

name_array = [
{"item": 1, "name": "John"}, 
{"item": 2, "name": "Barry"}, 
{"item": 3, "name": "Sally"}
]

filtered_array = name_array.filter((i) => i.item == 2)
delete filtered_array[0]
console.log(name_array)

Answer

Array#filter is immutable so you should console filtered_array value its working. No need to use delete. And change the condition == to !==

name_array = [{
    "item": 1,
    "name": "John"
  },
  {
    "item": 2,
    "name": "Barry"
  },
  {
    "item": 3,
    "name": "Sally"
  }
]

filtered_array = name_array.filter((i) => i.item !== 2)
console.log(filtered_array)
