* Theory:
  -JavaScript are unordered
  -Its elements are untyped, an array can contain different types of data
  -Arrays are 32-bit indexed so its index can be from 0-4294967294 (2^32 - 2)
  and its elements can go from 0 to 4.294.967.295

// Dynamic Sizing

console.log(names.length) // 2
names[10] = "Lucas"
