Can you tell me the differences between Array and ArrayList?
Answer Posted / Abhishek Raghav
JavaScript does not have an ArrayList class like Java. However, if we compare JavaScript's array with Java's ArrayList:nn- JavaScript arrays are fixed in size and grow dynamically when needed. In contrast, ArrayList is resizable.n- JavaScript arrays can hold different data types (numbers, strings, objects, etc.) whereas Java's ArrayList stores only objects.n- JavaScript arrays have a faster access time for elements since they are stored contiguously in memory. In contrast, ArrayList has slower access times because it uses linked nodes.
