Hi, i want to save an array `my_array = [1,2,3,4,5]` and replace a element from `my_array` with a value, but i don’t want to change my principal array.  
For example,

```julia
my_array = [1,2,3,4,5]
replace 2 for 8
new_array = [1,8,3,4,5]

```

Then, if print `my_array = [1,2,3,4,5]` and `new_array = [1,8,3,4,5]`  
Is there a function that does that?

Thanks!
