In computer programming and software design, code refactoring is the process of restructuring existing source code—changing the factoring—without changing its external behavior. Refactoring is intended to improve the design, structure, and/or implementation of the software (its non-functional attributes), while preserving its functionality.
Rule of three ("Three strikes and you refactor") is a code refactoring rule of thumb to decide when similar pieces of code should be refactored to avoid duplication. It states that two instances of similar code do not require refactoring, but when similar code is used three times, it should be extracted into a new procedure.
Function declarations, which declare a variable and assign a function to it, are similar to variable statements, but in addition to hoisting the declaration, they also hoist the assignment – as if the entire statement appeared at the top of the containing function – and thus forward reference is also possible: the location of a function ...

In JavaScript, objects are garbage collected if they are unreachable from the global object. [4] One way to make an object unreachable is to overwrite the variables or properties that reference it. let x = {}; // The variable x is declared and set to an object x = null ; // x is overwritten and the object becomes unreachable

It is also not scalable when there are multiple aspects to be applied on the same code and each aspect requires a different refactoring. [5] In general every aspect will be tightly coupled with an application's structure as the pointcuts explicitly contain a method's signature, so when an application changes the pointcut needs to be changed as ...
