Doing this so that I can document solutions for HackerRank for myself and discuss runtime complexities with other and try to come up with better solutions.
// solution
function simpleArraySum(n, ar) {
// Complete this function
return ar.reduce( function( acc, val ) {
return acc + val;
} );
}
I think using the native js reduce function is simple solution without using for loops.
