How to properly delete the first element in an array?

by user3332558   Last Updated December 06, 2018 14:28 PM

Is it possible to delete the first element of an array without shifting all elements later?

My guess is that I can remember the index of the 'current first element', like so:

uint[] public myArray;
uint firstElement;
delete myArray[firstElement];

but, is there a convention or something built in for this?
