InsertAt - A Simple Mixin

InsertAt is a very simple functional method for adding items at a specific point in a copy of the orignal array.

I DON'T THINK YOU NEED A LIB JUST FOR THIS. IT WAS SOME OLD CODE I WROTE, AND SOME PEOPLE ARE USING IT STILL.

How to Use

To use the InsertAt mixin:

1. Import the function into your project.

   import insertAt from 'insert-at';

2. Call the insertAt function with your array, the index at which to insert, and the item you wish to add. It will return a new array with the item inserted at the specified position.

   const originalArray = [1, 2, 3, 4];
   const newItem = 'a';
   const indexToInsert = 2;
   
   const newArray = insertAt(originalArray, indexToInsert, newItem);
   // newArray should be [1, 2, 'a', 3, 4]

You now have a new array with the item inserted at your specified index.
