Dead store : ウィキペディア英語版
Dead store
In computer programming, a local variable that is assigned a value but is not read by any subsequent instruction is referred to as a dead store. Dead stores waste processor time and memory, and may be detected through the use of static program analysis.
==Examples==
Java example of a dead store:

// DeadStoreExample.java
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
public class DeadStoreExample
}

In the above code an ArrayList object was instantiated but never used. Instead, in the next line the variable which references it is set to point to a different object. The ArrayList which was created when list was declared will now need to be de-allocated, for instance by a garbage collector.
JavaScript example of a dead store:

function func(a, b)

"The code in the loop repeatedly overwrites the same variable, so it can be reduced to only one call."
