I have this array:

my_json = [
    {
        "DontNeed":"Remove",
        "year":"2015",
        "Some name": "some value"

    },
    {
        "DontNeed":"Remove",
        "year":"2016",
        "Some name": "another value"
    },
];

I want to have that JSON like this:

new_json = [
    {
        "year":"2015",
        "Some name": "some value"

    },
    {
        "year":"2016",
        "Some name": "another value"
    },
];

Is there a way to do this? an known function?


You've tagged the question with javascript, so I'm assuming that you're looking for a JavaScript solution to this problem.

Presuming that your JSON is in an object of some kind (which I thought was called my_json), you can simply do something like:

for (var x in my_json) {
    delete x['DontNeed'];
}

Remove first name/value of each object in an array, Remove first name/value of each object in an array. remove specific element from array javascript javascript remove object from array array splice javascript  Removing Array Items By Value Using Splice If you know the value you want to remove from an array you can use the splice method. First you must identify the index of the target item. You then use the index as the start element and remove just one element.


Don't bother having more properties, leave it as it is.

If you really can't, then use Array.map function like this:

my_json = [
    { "DontNeed":"Remove", "year":"2015", "Some name": "some value" },
    { "DontNeed":"Remove", "year":"2016", "Some name": "another value" }
];

new_json = my_json.map(x => ({
    year: x.year,
    'Some name': x['Some name']
}));

console.log(new_json);

9 Ways To Remove 🗑️ Elements From A JavaScript Array [Examples], How do you remove the first element of a JavaScript array? The shift Now when you execute the loop it will remove every matching item. One way to remove an object from a fixed-size array is to create a new array that includes only selected objects from the original array. In this command, we use a ForEach loop go through every letter in the $letters array. We add all of the objects in $letters to the $newLetters array, except for “c”.


You can use the delete operator to remove a known key (in this case property) from an object. Combined with the map function you can quickly remove the property from all entries.

var my_json = [
    {
        "DontNeed":"Remove",
        "year":"2015",
        "Some name": "some value"

    },
    {
        "DontNeed":"Remove",
        "year":"2016",
        "Some name": "another value"
    },
];
var expected = my_json.map(j => {
  delete j['DontNeed']
  return j;
});
console.log(expected);

Remove Element from an Array in JavaScript, To remove a particular element from an array in JavaScript we'll want to first find For example, maybe you want to remove all "people" objects from an array if  If you want to find an array contains a certain value, you don’t have to iterate through elements to compare the values with search term. Instead, you can apply filter with various comparison operators directly to the array.


You can destructure off the property (or properties) you don't want and make a new array with map():

let my_json = [
    {"DontNeed":"Remove","year":"2015","Some name": "some value"},
    {"DontNeed":"Remove","year":"2016","Some name": "another value"}
];

let new_json = my_json.map(({DontNeed, ...rest}) => rest)
console.log(new_json)

Array methods, The arrays are objects, so we can try to use delete : That's natural, because delete obj.key removes a value by the key . forEach method allows to run a function for every element of the array. id : 3 , name : "Mary" } ] ; // returns array of the first two users let someUsers = users . filter ( item => item . id < 3 )  The $.each() function is not the same as $(selector).each(), which is used to iterate, exclusively, over a jQuery object. The $.each() function can be used to iterate over any collection, whether it is an object or an array. In the case of an array, the callback is passed an array index and a corresponding array value each time.


Objects, The first property has the name "name" and the value "John" . Makes it easier to add/remove/move around properties, because all lines become alike. Object Objects are associative arrays with several special features. Array.splice (start_index, number_of_elements_to_remove); start_index refers to the position in the array where the Insertion or Removal of elements will begin. number_of_elements_to_remove will begin at the start index, and remove an element from array


.map(), Description: Pass each element in the current matched set through a function, producing a new jQuery As the return value is a jQuery object, which contains an array, it's very common to call <input type="text" name="url" value="https://​johnresig.com/"> Make the first item all caps Delete the second and fourth items. Note: trying to remove items from an array while you are enumerating through it will make a real mess of your code. I'd make a 2nd arrayList, identical to the 1st, and then iterate through that one.
