Slice and Splice

Programming
1

I’m wondering why in the following code is the arr2 variable changing if i am using the slice function on the newArr2 variable?


function frankenSplice(arr1, arr2, n) {
  let newArr = [];
  
let newArr2 = arr2;

newArr = newArr2.splice(n, 0,...arr1)
console.log(arr2)
  return newArr2;
}

frankenSplice([1, 2, 3], [4, 5, 6], 1);
3

its creating a new variable to equal arr2 so i dont perform the splice on the original arr2 array.

Alright i got it and used slice on the array. Yeah i still havent mastered all of the commands and should go over them again. I probably rushed through the lessons too fast. I am new to programming so all this is still pretty tricky to me.

thanks for the help
