Utilize Javascript to establish a fresh attribute by analyzing other attributes contained in an array within the object

Currently, I am working on a data structure that looks like this:

masterObject: {
  Steps: [
    {
      step: {
        required: false,
      },
      step: {
        required: false,
      },
      step: {
        required: false,
      },
    },
  ]
}

My goal is to iterate through the array of steps and verify if each step object contains the 'required' property set to false. If all steps are indeed not required, then I want to add a new property to the masterObject called

masterObject.isObjectWithNoRequiredSteps = true;

Once this code snippet runs, the updated masterObject will resemble this:

masterObject: {
  Steps: [
    {
      step: {
        required: false,
      },
      step: {
        required: false,
      },
      step: {
        required: false,
      },
    },
  ]
  isObjectWithNoRequiredSteps: true
}

If there is an instance where one of the step objects has the required property set to true, then I want to update the new property to false like so:

masterObject.isObjectWithNoRequiredSteps = false;

masterObject: {
  Steps: [
    {
      step: {
        required: true,
      },
      step: {
        required: false,
      },
      step: {
        required: false,
      },
    },
  ]
  isObjectWithNoRequiredSteps: false
}

I am seeking advice on the best method for implementing this functionality at the higher level object.

Answer №1

The Steps array contains objects with multiple attributes or keys named step, which is invalid in JavaScript. It is recommended to adjust the data structure as shown below

masterObject: {Steps: [{ 
    step1: { required: false, }, 
    step2: { required: false, }, 
    step3: { required: false, },
}, ] }

To check if each step within the Steps array has a value of false for the "required" attribute, you can use the following code snippet

masterObject.isObjectWithNoRequiredSteps = Object.keys(masterObject.Steps[0]).reduce(function(result, nextStep){
const isRequired = masterObject.Steps[0][nextStep].required; 
return !isRequired && result; 
}, true);
