What is a more efficient method for identifying a single, specific object without using the index approach demonstrated here?

I need to verify if the taskDetails object contains only the lastTask value and no other values.

To achieve this, I am currently using the approach with index [0] as shown below:

Object.keys(this.clubdetails.taskDetails)[0]==["lastTask"]

However, I have a concern that adding another object like "currentTask" at index 1, the index of lastTask would still be ["0"]. This means that my current check for lastTask at index[0] would return true even though there are other values in taskDetails besides lastTask.

I believe there should be a more effective method to confirm if an object contains only a specific value and nothing else. Any advice on how to achieve this?https://i.sstatic.net/m092X.png

Answer №1

To determine if the object keys contain only one value, you can verify the length of the keys:

if (Object.keys(this.clubdetails.taskDetails).length === 1 && Object.keys(this.clubdetails.taskDetails)[0] === "lastTask") {
    // Your code here
}

Answer №2

Transforming the keys of this.clubdetails.taskDetails into a string and comparing it with ["lastTask"] results in JSON.stringify(Object.keys(this.clubdetails.taskDetails)) === JSON.stringify(["lastTask"])

The main objective is to convert the Object.keys(this.clubdetails.taskDetails) into a string. If the only key present is lastTask, then the converted string should be ["lastTask"]
