![]() The second object ob2 is not directly reachable, but it is reachable from root object ob1. Now there is another reference in ob1, which is pointing to ob2. For instance, consider we have an object ob1, as our global object. When some other values which are reachable from the roots are also marked as reachable. ![]() These directly reachable objects are called root objects. Not only that function, the parameters and local variables of these functions in the chain will be reachable. If some other functions can be called from the currently executing function can also be reachable. When a function is executing currently, then its local variables and parameters are directly reachable. There are a few possible ways to determine whether an object is reachable or not− An object can be reachable from some location directly or indirectly. When a value or memory location is reachable from some point then that will not be removed. In this mode, the garbage collector tries to search for reachable values from some point. The first concept of memory management is reachability. Interlinked Objects (interconnections between different objects) There are a few important parts that we are going to discuss in detail− In this article, we shall discuss how garbage collection (GC) works in JavaScript. Unlike low-level languages, JavaScript automatically detects which objects will be needed in later cases and which will be garbage that is occupying memory without any reason. JS Graphics JS Graphics JS Canvas JS Plotly JS Chart.js JS Google Chart JS D3.Memory management in JavaScript is much easier than in low-level languages like C or C++.
