Creating anarrayin JavaScript is easy. We create an array using thevarkeyword. It is similar to the way we create an Array usingArrayListin Java. Java insists on specifying the data type of theArrayList. But in JavaScript, we do not explicitly declare the data type of the Array. We let...
and it is simple and clean. The upside of usingStreamis that it gives you access to useanyMatchandnoneMatch. The downside of usingStreamis that it creates potentially unnecessary garbage. With JDK Collections, the collections that we can avoid creating anIteratororStreamareArrayListand anyRandomAcc...
