Arrays are implemented so that only the defined elements use memory; they are "sparse arrays". Setting myArray [10] = 'someThing' and myArray [57] = 'somethingOther' only uses space for these two elements, just like any other object. The length of the array will still be reported as 58.
Enhancements to the DOM, enabling developers to easily add, modify, select, and delete DOM elements. Storing and retrieving information with Element storage is also supported. [9] The framework includes built-in functions for manipulation of CSS, DOM elements, native JavaScript objects, Ajax requests, DOM effects, and
That is, if there is a sorting algorithm which can sort in O(S) time per key, where S is some function of n and word size, [22] then one can use the given procedure to create a priority queue where pulling the highest-priority element is O(1) time, and inserting new elements (and deleting elements) is O(S) time.
The best you can do is (in case of array implementation) simply concatenating the two heap arrays and build a heap of the result. [13] A heap on n elements can be merged with a heap on k elements using O(log n log k) key comparisons, or, in case of a pointer-based implementation, in O(log n log k) time. [14]
Regardless of how many elements are already contained, a new element can always be added. It can also be empty, at which point removing an element will be impossible until a new element has been added again. Fixed-length arrays are limited in capacity, but it is not true that items need to be copied towards the head of the queue.
