Introduction: Arrays in Java and C++ are data structures, that are of fixed-size contiguous and store homogeneous data. These arrays utilize contiguousness and caching to improve performance thus reducing the random access time. However, JavaScript arrays are different beasts. Unlike typical arrays, they are dynamic, sparse, and non-homogeneous. This at first gives a presumption of their low performance(due to the inability of caching features), but under the hood things are different. Javascript engines are incredibly clever beasts. Whenever the data is not sparse and is homogeneous, transparently Javascript stores them in contiguous blocks of memory. Thus behaving a little like typical arrays and giving us improved performance....
