You can use the indexOf method like this:
var index = array.indexOf(item);
if (index !== -1) {
array.splice(index, 1);
}
Note: You'll need to shim it for IE8 and below
var array = [1,2,3,4]
var item = 3
var index = array.indexOf(item);
array.splice(index, 1);

Removing elements from an array - JavaScript - SitePoint Forums | Web Development & Design Community
November 2, 2017 - What I am trying to achieve is that after the first click the elements are removed so it must always have 3 · Wouldn’t it be easier to simply assign a new array then? ^^ If you want to implement something that behaves similar to a circular queue though, a possible solution might go like · const pushCyclic = (array, ...values) => array.concat(values).slice(-array.length) const myArray = [1, 2, 3] pushCyclic(myArray, 4) // -> [2, 3, 4] pushCyclic(myArray, 4, 5) // -> [3, 4, 5] pushCyclic(myArray, 4, 5, 6) // -> [4, 5, 6] pushCyclic(myArray, 4, 5, 6, 7) // -> [5, 6, 7]
Why is removing a specific element from an array so needlessly complicated in Javascript?
You could use the .filter method. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter Use it like this: const newArray = array.filter(element => element > 6) The 'element > 6' is just a placeholder example. If your array was a series of numbers, it would only return numbers that are greater than six. If you wanted it to remove a certain word from an array of words you could switch that conditional statement out with "element !== 'word' " 'newArray' will be your array without the value you're trying to remove. 'Array' represents the current array with the value you're trying to remove More on reddit.com

September 10, 2014Is it possible to remove individual values from an file input multiple element?
So far as defined in the FileList API I don't think this is possible. Are you trying to block a certain type of file, client side? Perhaps it would be better to just define what types of file you want to allow via markup, e.g. http://dev.w3.org/html5/spec/number-state.html#attr-input-accept More on reddit.com

August 17, 2011Overwrite array in object array by value of a key?
For more advanced object and array manipulation, lodash can really help: http://lodash.com/ Highly recommend taking a look. But in vanilla JS, you could do: var people = [ {"name": "Dave" , "owns":["House", "Car", "Boat"]}, {"name": "Mike" , "owns":["Dog", "House", "TV"]}, {"name": "Fred" , "owns":["Sofa", "Elephant", "Space Station"]}, {"name": "Larry" , "owns":["Land", "Coins", "Iron Lung"]} ]; function updateOwnership(name, objects) { for (var i = 0; i < people.length; i++) { if (people[i].name === name) { people[i].owns = objects; break; } } } updateOwnership('Fred', ["Guitar", "Flowers", "Socks"]); console.log(people); More on reddit.com

A one-liner will do it,
var arr = ['three', 'seven', 'eleven'];
// Remove item 'seven' from array
var filteredArray = arr.filter(function(e) { return e !== 'seven' })
//=> ["three", "eleven"]
// In ECMA6 (arrow function syntax):
var filteredArray = arr.filter(e => e !== 'seven')
This makes use of the filter function in JS. It's supported in IE9 and up.
What it does (from the doc link)
filter() calls a provided callback function once for each element in an array, and constructs a new array of all the values for which callback returns a value that coerces to true. callback is invoked only for indexes of the array which have assigned values; it is not invoked for indexes which have been deleted or which have never been assigned values. Array elements which do not pass the callback test are simply skipped, and are not included in the new array.
So basically, this is the same as all the other for (var key in ary) { ... } solutions, except that the for in construct is supported as of IE6.
Basically, filter is a convenience method that looks a lot nicer (and is chainable) as opposed to the for in construct (AFAIK).

How to Remove Elements from a JavaScript Array · CoreUI
February 13, 2025 - In many real-world applications dealing with JavaScript objects and arrays, you might need to remove array elements based on user input or a dynamically generated condition. By using methods like splice or filter, you can handle different methods of removal gracefully. For instance, if you must remove an element of the array with a specified value, consider filter.

January 17, 2023 -
I'm just looking for something along the lines of:
array.remove("element")Upon Googling for solutions so far I've found
Remove an element at any index with splice
Remove an element from an array with a for loop and push
Remove an element at any position of an array with slice and concat
There's more but I'm assuming you get the point. Why is this seemingly simple task so ridiculously complicated with Javascript?
Did nobody think to include a ".remove()" method when they were first developing Javascript? Is there a quirk of the language that makes it impossible? What is the reason for this?

I mean the easy answer is: array.splice(array.indexOf("element"), 1); But there's a lot of things that cannot be added to JavaScript due to naming reasons and backwards compatibility. In the early days of JavaScript, it was the wild west. People made and used libraries that did awful things. Notably they extended prototypes. So there's a ton of code floating around for Array.prototype.remove implementations. If a real implementation was added, then these libraries might break in some way. You can see a discussion on this exact method here . This is not the only occurrence of this. Take a look at smooshgate for the most famous example of this.

April 12, 2024 - The arrow function fruit => fruit !== 'banana' acts as the condition, where only elements that don't match 'banana' are included in the new array. The filter() method is a safer option than splice() because it doesn't modify the original array. Sometimes, you might need to remove an item from an array based on its value rather than its index.

The original array numbers is modified to only include odd numbers [1, 3, 5]. The removed array contains the even numbers [2, 4, 6] that were removed. The Lodash _.remove method is particularly useful for remove element from array JavaScript tasks where elements need to be removed based on specific criteria, offering both modification of the original array and access to the removed items.
