Question

What is the method for adding information to this object?

input:

[{ 
    email: 'sassa', 
    password: 'sas' 
}]

output:

[{ 
    email: 'sassa', 
    password: 'sas' ,
    valid: true
}]

I have a response coming from my Node.js server, and I need to add the 'valid' field to the object for future use. What is the best way to achieve this? Using push doesn't seem to be working as expected.

Method 1: Utilizing the Object Spread Operator (A concise and modern approach)

const initialData = { 
    name: 'John', 
    age: 30
}

const updatedData = {...initialData, status: 'active'}

console.log(updatedData) // produces {name: "John", age: 30, status: "active"}

Method 2: Implementing Object Assign (Compatible with various systems)

const initialData = { 
    name: 'John', 
    age: 30
}

const updatedData = Object.assign(initialData, {status: 'active'})

console.log(updatedData)

Just like @AbdulBasit pointed out, the push() method is specifically for adding elements to arrays and not dictionaries.

In this case, you need to initialize the value of valid as null or false before setting it to true.

var dictionary = {
  email: "myemail",
  password: "mypassword",
  valid: null
};
dictionary.valid = true;
if (dictionary.valid) {
  document.write("The 'valid' property has been set to true.");
}
