Scala - Memory Management

Since Scala runs on Java Virtual Machine, JVM’s garbage collect is responsible of clearing up Scala program’s memory when it becomes obsolete. At this note, we can say that Scala’s memory management schema is relatively the same as Java. Every time an object is instantiated at run-time, Scala reserves some memory to hold the objects states; which includes its variables. Memory leak is also being prevented from JVM’s run-time environment.
However, on a side note, since Scala comes with many powerful built-in functions (such as filter, mapping), developer might be using more memory that they needed. These functions often generates new objects which many costing additional memory usage.
