var x1 = 0; // A global variable, because it is not in any function let x2 = 0; // Also global, this time because it is not in any block function f {var z = 'foxes', r = 'birds'; // 2 local variables m = 'fish'; // global, because it wasn't declared anywhere before function child {var r = 'monkeys'; // This variable is local and does not affect the "birds" r of the parent function. z ...

Some deque implementations use array deques, which allow amortized constant time insertion/removal at both ends, instead of just one end. Goodrich [ 16 ] presented a dynamic array algorithm called tiered vectors that provides O ( n 1/ k ) performance for insertions and deletions from anywhere in the array, and O ( k ) get and set, where k ≥ 2 ...
