One thing I would suggest, is that unless you need those files right at startup, try to load only when you need them. EDIT: Refer to the post above. Luckily for you, Node.js comes with a garbage collector, and you don't need to manually manage memory allocation. Garbage collection is a way of managing application memory automatically. The job of the garbage collector (GC) is to reclaim memory occupied by unused objects (garbage). It was first used in LISP in 1959, invented by John McCarthy. Parameters and variables for other functionson the nested callsâ current chain. See Full Salary Details ». Another view would be, that garbage collection is inlined at compile time.
