In the memory management of Ja*aScript, you can find out how much memory you have It runs automatically invisibly to us. We all use memory when declaring primitive types of variables, objects, or functions. What if these things are no longer needed? How do the Ja*aScript engine find and delete these? The main concept of Ja*aScript memory management is accessibility. In short, an accessible value means that it is somehow accessible or usable. They consider what is kept in memory to be variables and parameters accessible to the current scope chain. For example, if a local variable refers to a specific object and the object has a property that refers to another object, the object is considered reachable. And the garbage collector, which acts as a background process for the Ja*aScript engine. It monitors all objects and performs deletion when they become inaccessible. The arrows shown here represent object references. The global variable user refers to the {name: John} object. (Here we will shortly call John). The name property of the zone is stored inside the object, saving the primitive type. Here, when we overwrite the value of user, the reference is now inaccessible to the zone. There is no way to approach it, and no one refers to John. The garbage collector reclaims the data and empties the memory. Now, imagine that you copied the reference to the user as admin. Now we will do the same thing again.
