Slicing arrays is very simple using the slice primitive
Slices from 1st element to 3rd element (not inclusive)
let array = [1, 2, 3, 4, 5];
let slice = &array[1..3];
Result : [2, 3]
We can also copy the rest of the array from a index
let array = [1,2,3,4,5];
let slice = &array[2..];
Result : [3, 4, 5]
Or to a index(not inclusive)
let array = [1,2,3,4,5];
let slice = &array[..2];
Result : [1, 2]
We can do the same thing with strings
let greeting = "Hello Crunchskills🍫";
let crunchskills = &greeting[6..];
Result : "Crunchskills🍫"
