"Uncaught TypeError: Array.removeAt() is not a function",

Question

I got a MSDN document for Array.removeAt() function.

But when i trying it, I am getting this error : "Uncaught TypeError: Array.removeAt is not a function",

var a = ['a', 'b', 'c', 'd', 'e'];
Array.removeAt(a, 2);
console.log(a);

Why it's not working here? And is that is a wrong document?

Edit: a.removeAt(a, 2); also not working.

var a = ['a', 'b', 'c', 'd', 'e'];
a.removeAt(a, 2);
console.log(a);

Answer 1

There is no Array.removeAt() function in JavaScript.

MSDN article is an out of date reference to a JScript (not JavaScript) function.

Alternatively you can use Array.splice() or some other similar functions.
