Garbage collected languages help developers manage memory by periodically checking which previously allocated pieces of memory can still be "reached" from other parts of the application. JavaScript is one of the so called garbage collected languages. Wikipedia has good articles on manual and automatic memory management. Others expect developers to be completely explicit about when a piece of memory is unused. Certain programming languages provide features that help developers do this. In other words, only developers can make it clear whether a piece of memory can be returned to the operating system or not. However, whether a certain piece of memory is unused or not is actually an undecidable problem. These ways may reduce the chance of leaking memory. Programming languages favor different ways of managing memory. In essence, memory leaks can be defined as memory that is not required by an application anymore that for some reason is not returned to the operating system or the pool of free memory. Leaks are the cause of whole class of problems: slowdowns, crashes, high latency, and even problems with other applications. Even when working with memory-managed languages there are cases where memory can be leaked. Memory leaks are a problem every developer has to face eventually. We will also learn how to use the Chrome Development Tools to find them. In this article we will explore common types of memory leaks in client-side JavaScript code.
