Ruby array sort.
In the first form if no arguments are sent the new array will be empty.
Ruby arrays are not as rigid as arrays in other languages.
Sort with blocks sort in descending order and sort in place.
This means that the original array will change instead of creating a new one which can be good for performance.
An array of sorted elements.
A negative index is assumed relative to the end of the array that is an index of 1 indicates the last element of the array 2 is the next to last element in the array and so on.
Once you have data in an array you can sort it remove duplicates reverse its order extract sections of the array or search through arrays for specific data.
Notice that sort will return a new array with the results.
Ruby arrays can hold objects such as string integer fixnum hash symbol even other array objects.
The ruby sort method works by comparing elements of a collection using their operator more about that in a second using the quicksort algorithm.
It s also possible to sort in place using the sort.
Returns a new array.
You can also pass it an optional block if you want to do some custom sorting.
Let us see an example.
Ruby sort arrays use the sort method.
You can also convert an array to a string transform one array of data into another and roll up an array into a single value.
