Even coming from javascript this looks atrocious to me:
irb >> a = ['a', 'b', 'c'] => ["a", "b", "c"] >> a.unshift(a.delete('c')) => ["c", "a", "b"] Is there a more legible way placing an element to the front of an array?
Edit my actual code:
if @admin_users.include?(current_user) @admin_users.unshift(@admin_users.delete(current_user)) end

To change the position of an element in an array:Use the splice() method to insert the element at the new index in the array. The splice method changes the original array by removing or replacing existing elements, or adding new elements at a specific index.
Ruby | push() function The push() function in Ruby is used to push the given element at the end of the given array and returns the array itself with the pushed elements. Parameters: Elements : These are the elements which are to be added at the end of the given array. Returns: the array of pushed element.
The first() is an inbuilt method in Ruby returns an array of first X elements. If X is not mentioned, it returns the first element only. Parameters: The function accepts X which is the number of elements from the beginning. Return Value: It returns an array of first X elements.
Maybe this looks better to you:
a.insert(0, a.delete('c')) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
