Same way as you would in JavaScript.
delete myArray[key];
Note that this sets the element to undefined.
Better to use the Array.prototype.splice function:
const index = myArray.indexOf(key, 0);
if (index > -1) {
myArray.splice(index, 1);
}

Array.prototype.splice() - JavaScript | MDN
An integer indicating the number of elements in the array to remove from start. If deleteCount is omitted, or if its value is greater than or equal to the number of elements after the position specified by start, then all the elements from start to the end of the array will be deleted. However, if you wish to pass any itemN parameter, you should pass Infinity as deleteCount to delete all elements after start, because an explicit undefined gets converted to 0.

r/learnprogramming on Reddit: Why is removing a specific element from an array so needlessly complicated in Javascript?
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.
