Programming Best Practices: Memory Efficiency with Closures [I] - Gireesh Punathil, IBM India Pvt Ltd

Memory Leaks leading to undesired growth and exhaustion of memory are by far the most common production problem reported on enterprise scale Node applications. Closures, a powerful semantic feature in functional programs which are used pervasively in Node.js/Javascript programs to support their asynchronous and event driven programming model, are a prominent source of unanticipated memory leaks.
In this presentation, I will explain three of the most common use cases where Closures are used in Node. For each of the use cases, I will explain a) sample code, b) the life-span of the Closure context and which variables the closure keeps live, iii) what memory will be retained during the life-span of the Closure.
