Creating randomized sample information within a defined timeframe using JavaScript

Question

Creating randomized sample information within a defined timeframe using JavaScript

I'm looking to create mock data following a specific structure.

Criteria:

The time interval for start and end times should be either 30 minutes or 1 hour.

Need to generate 2-3 mock entries for the same day with varying time intervals.

 [{
    Id: 1,
    Subject: 'Bob',
    StartTime: new Date(2020, 6, 11, 9, 30),
    EndTime: new Date(2020, 6, 11, 11, 0),
    CategoryColor: '#1aaa55'
}]

Below is the code snippet I have so far for generating this mock data,

However, I'm unsure about how to implement the data logic. Any assistance would be appreciated.

function random() {
  for (let index = 0; index <= 100; index++) {
    let x = {
      Id: getRandomInt(1, 1000),
      Subject: generateName(),
      StartTime: new Date(2020, 6, 11, 9, 30),
      EndTime: new Date(2020, 6, 11, 11, 0),
      CategoryColor: getRandomColor()
    }
    data.push(x);
  }
}

If you're looking for a tool to generate random names, check out this link. For generating random numbers, you can utilize the Math.random() function (which gives a value between 0-1) in conjunction with Math.floor(). Here's an example:

Math.floor(Math.random() * 101);  // generates a random integer from 0 to 100

To create random dates, refer to this resource.

If you want to specify an interval, follow this format:

let generated_data = []; // stores the final data
let colors = ["Blue", "Red", "Green"]; // define the colors needed


function getRandomInt(min, max) { // generates random number
    return Math.floor(Math.random() * (max - min)) + min;
}

function capFirst(string) { // capitalizes the first letter of a string
    return string.charAt(0).toUpperCase() + string.slice(1);
}


function generateName(){ //outputs random name
    var name1 = ["abandoned","able","absolute","adorable"];
    var name2 = ["people","history","way","art","world"];
    var name = capFirst(name1[getRandomInt(0, name1.length)]) + ' ' + capFirst(name2[getRandomInt(0, name2.length + 1)]);
    return name;
}


function randomDate(date1, date2){ //creates random date
    var date1 = date1 || '01-01-1970'
    var date2 = date2 || new Date().toLocaleDateString()
    date1 = new Date(date1).getTime()
    date2 = new Date(date2).getTime()
    if( date1>date2){
            return new Date(getRandomInt(date2,date1)).toLocaleDateString()   
    } else{
        return new Date(getRandomInt(date1, date2)).toLocaleDateString()  
    }
}

function generateRandomObject() { //appends a random object in the list
    let obj = {
        Id: getRandomInt(1, 1000),
        Subject: generateName(),
        StartTime: randomDate('01/01/2000', '01/01/2020'),
        EndTime: randomDate('01/01/2000', '01/01/2020'),
        CategoryColor: colors[getRandomInt(0, colors.length)]
    }
    generated_data.push(obj);
}


setInterval(generateRandomObject, 30 * 60 * 1000); //executes the function at 30-minute intervals
