Ways to create two separate references pointing to a single object

Question

Ways to create two separate references pointing to a single object

Here is the code I am currently running:

function TypeOfCar(vehicle) {
  this.vehicle = vehicle;
}

var sedan = new TypeOfCar('sedan');
var carType = race;
console.log(carType);
console.log(sedan);

After running the code, the output is as follows:

[object Object]
TypeOfCar {vehicle: "sedan"}

Why does carType produce a different result from sedan? When using '==' comparison they are considered equal, but with '===' comparison, they are not. How can I ensure that carType and sedan reference the same object?

Answer №1

The variable status contains a string value, whereas the variable race holds an object.

If you apply the typeof operator to both variables, you will observe this distinction.

My intuition suggests that the reason for this discrepancy is due to the fact that status is likely reserved for window.status, but I may be mistaken.

It appears that you are experiencing an issue with window.status.

To resolve this conflict, consider renaming the variable or placing it within a more localized scope.

I have tested it and found that it functions properly, returning the identical object in both instances.

You can view a demonstration on my CodePen

If you are attempting to execute this in a web browser console, there may be a conflict with the window object within the global scope.

The issue lies in the code you provided. Although your logic seems correct, there is a problem with using "status" as a variable name since it is already a global variable in JavaScript (part of the window object). However, if you adjust the variable name, everything should work properly.

function Status(type) {
  this.type = type;
}

var raceStatus = new Status('race');
var status2 = raceStatus;
console.log(status2);
console.log(raceStatus);

It appears that you have used the same name for both Object and var. It is recommended to change the name of the var to avoid confusion.

function Status(type) {
      this.type = type;
    }

var race = new Status('race');
var getStatus = race;
console.log(getStatus);
console.log(race);

Result: { "type": "race" } { "type": "race" }
