Different JavaScript entities with identical attributes (labels)

Different JavaScript entities with identical attributes (labels)

Even though JavaScript doesn't have tangible objects, I'm struggling to differentiate between them.

Let's say we have two objects called Apple and Orange defined as follows:

function Apple(){
    this.name = "Apple";
}

and

function Orange(){
    this.name = "Orange";
}

From an OOP perspective, the name attributes of Apple and Orange are not related since they belong to different classes.

My issue/question is that when I rename the name property in the Apple class, ReSharper prompts me to also rename the property in the Orange class. Furthermore, pressing F12 (GOTO DEFINITION) shows both properties.

Why does this happen? Are they declared in the global scope? How can I make sure Apple and Orange are distinct objects?

Answer №1

ReSharper is designed to adapt to how you plan on utilizing functions such as "Apple" and "Orange". It takes an approach of searching for all potential dynamic uses of a symbol to ensure accurate functionality. Here's an example to illustrate this concept:

function Apple(){
    this.name = "Apple";
}

function Orange(){
    this.name = "Orange";
}

var x = {name: "Tomato" };

Apple.call(x);

alert(x.name);

Orange.call(x);

alert(x.name);

If you decide to change the name of one 'name' item but not the others within your code, it could lead to errors. It is recommended to rename all instances for consistency.

This is why ReSharper identifies all three usages in such scenarios, giving you control over which ones to rename based on your specific code semantics.
