create a pregnancy system in javascript

To create a pregnancy system in javascript you will need to simulate the various stages of pregnancy and create a set of rules for the progression of the pregnancy. Here are the general steps to get started:

Define a set of variables to store the current state of the pregnancy: the current stage (e.g. first trimester, second trimester), the current week, and any other relevant data such as the due date.


index.tsx
let currentStage = "first trimester";
let currentWeek = 0;
let dueDate = null;

Create a function to progress the pregnancy every week. This function should take into account the current stage of the pregnancy and update the variables accordingly. For example, if the pregnancy is in the first trimester, the function would progress to the second trimester after 12 weeks.


index.tsx
function progressPregnancy() {
  if (currentStage === "first trimester") {
    if (currentWeek >= 12) {
      currentStage = "second trimester";
    }
  } else if (currentStage === "second trimester") {
    if (currentWeek >= 28) {
      currentStage = "third trimester";
    }
  } else {
    // handle third trimester rules
  }
  currentWeek++;
}

Add any additional rules for the pregnancy such as how the due date is calculated or any events that may happen during pregnancy (e.g. morning sickness in the first trimester).


index.tsx
// calculate the due date based on the start date
function calculateDueDate(startDate) {
   dueDate = new Date(startDate.getFullYear(), startDate.getMonth() + 9, startDate.getDate());
   return dueDate;
}

// add a check for morning sickness
function checkMorningSickness() {
  if (currentStage === "first trimester" && (currentWeek >= 4 && currentWeek <= 12)) {
    if (Math.random() < 0.5) {
      console.log("You feel nauseous and may experience morning sickness.");
    }
  }
}

Use these functions to simulate the pregnancy over time, such as in a setInterval loop in a web application.


index.tsx
calculateDueDate(new Date(2022, 2, 26));
let interval = setInterval(() => {
  checkMorningSickness();
  progressPregnancy();
  console.log(`Current stage: ${currentStage}. Week ${currentWeek}. Due date: ${dueDate}`);
  
  if (currentStage === "third trimester" && currentWeek === 40) {
    console.log("The baby is ready to be born!");
    clearInterval(interval);
  }
}, 1000 * 60 * 60 * 24 * 7); // progress once a week

This is a basic example, but you can add more complexity and detail as needed. Remember to handle any possible edge cases and think about how to represent the pregnancy visually if needed.
