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);
console.log(array) Top answer 1 of 16

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).

Why is removing a specific element from an array so ...
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?

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

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.
How do I remove from an array those elements that exists in another array?
All you need is a simple filter function, or you could just manually loop over the array. var filteredPeople = people.filter(function(element) { return peopleToRemove.indexOf(element) === -1; }); More on reddit.com

January 17, 2023Remove item from this.state.users
it is really annoying because every god damn thing in JavaScript is destructive and you really don't want to use destructive methods on your state What I did was have a function to remove that filtered the list based on index, and setState to that list (ES6 syntax): removeItem(index) { this.setState({ items: this.state.items.filter((x,i) => i != index }) }); } and then when you're generating your items to render, let rendered = this.state.items.map( (x, i) => ); More on reddit.com
