What is the drawback of creating true private in JavaScript?

The primary drawback of creating true private methods in JavaScript is that they can lead to memory inefficiency. This inefficiency arises because a separate copy of the private method is created for each instance of the class. This means that if you have multiple instances of a class, each one will have its own copy of the private method, consuming more memory than if the method were shared among all instances[3][5].

Additionally, the use of true private methods can introduce challenges in terms of code flexibility and maintenance. For example, private methods and fields in JavaScript are not accessible outside of the class they are defined in, which can make debugging and extending the class more difficult. This strict encapsulation prevents other parts of the code from accessing these methods, which can be a limitation when you need to modify or interact with these methods from outside the class[2][4].

Moreover, the implementation of true private methods in JavaScript, using the # syntax, can lead to compatibility issues. Not all JavaScript environments or tools support this syntax yet, which can cause problems when running code across different browsers o...
