Array slice
slice() is used to create a shallow-copied subset of an Array. (See Arrays).
Slice takes in the inclusive (up to and including) start index and the exclusive (up to) end index, and returns a shallow copy of the array with all elements outside of the range omitted.
js
const fruitsAndNuts = ["Banana", "Apple", "Mango", "Macadamia", "Almond", "Chestnut"];
// Here 0 is the first index, and 2(+1 = 3) is the last index
const fruits = fruitsAndNuts.slice(0, 3); // ["Banana", "Apple", "Mango"]
// Using a negative index will count backwards
const nuts = fruitsAndNuts.slice(-3); // ["Macadamia", "Almond", "Chestnut"]
// Using an index AND a negative index will count from the starting index to the distance from the end
// Here, Mango is the 2-index item, and Macadamia is the -2-index end
const expensive = fruitsAndNuts.slice(2, -2); // ["Mango", "Macadamia"]
