How do I remove an array item in TypeScript?

arrays, collections, typescript

Solution

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);
}

Problem

I have an array that I've created in TypeScript and it has a property that I use as a key. If I have that key, how can I remove an item from it?
