How to insert randomly entries of an array in another array react native

Question

Let's says I have this array : const numbers = [1,2,3,4,5];

And this array: const letters = ['A','B','C'];

I want to put 'letters' entries inside 'numbers' randomly. I don't care about the order of 'letters', but I want 'numbers' to keep the order. The goal is to have this kind of array :

const randomLettersInNumbers = [1, 'B', 2, 3, 'A', 4, 'C', 5];

How can I achieve this ?

const numbers = [1,2,3,4,5];
const letters = ['A','B','C'];
let randomLettersInNumbers = numbers
letters.forEach((item) => {
  let index = Math.floor(Math.random() * randomLettersInNumbers.length)
  randomLettersInNumbers.splice(index, 0, item)
})
