Recursion: A Morning Routine Explained Through JavaScript Functions
Published: 2023-08-24 08:36:20

## Introduction:
In the realm of programming, the concept of functions is vital for breaking down tasks into manageable blocks of code. This article will illustrate the power of functions by taking you through a simple morning routine coded in JavaScript. We'll explore how these functions interact and collaborate to create a coherent sequence of actions.

```javascript
function TakeShower(){
  return "Showering ";
}

function EatBreakfast(){
  let meal = CookFood();
  return `Eating ${meal}`;
}

function CookFood(){
  let items = ['bread','banana','milk','vegetable'];
  return items[Math.floor(Math.random()*items.length)];
}

function WakeUp(){
  TakeShower();
  EatBreakfast();
  console.log('Ok, ready to go to work');
}
```

Understanding the Functions:
Let's break down each function and its role in this morning routine.

1. **TakeShower():**
   This function represents the first step of the routine – taking a shower. It returns the string "Showering ", indicating that the user is in the process of showering. However, note that the function doesn't log or display this message anywhere.

2. **EatBreakfast():**
   The EatBreakfast() function models the second step: having breakfast. Inside this function, we call the CookFood() function to prepare a meal. We then use template literals to create a string that incorporates the returned meal. The result might be "Eating bread" or "Eating banana," depending on the randomized choice of food.

3. **CookFood():**
   The CookFood() function simulates cooking by generating a random item from an array of possible foods. The array contains items like 'bread', 'banana', 'milk', and 'vegetable'. The Math.random() method is used to select a random index from the array, ensuring a different meal each time.

4. **WakeUp():**
   This function represents the beginning of the routine. Inside WakeUp(), we call TakeShower() and EatBreakfast(). However, there's a key point to note here. These function calls are made, but their return values aren't captured or utilized. In essence, they happen, but the output isn't utilized further.

   Finally, a log message is printed to the console, indicating that the user is now ready to go to work.

## Execution:
The sequence of function calls is initiated by invoking WakeUp(). However, while TakeShower() and EatBreakfast() are called, their return values aren't being utilized in the current code. This is an important aspect to understand – functions execute, but if their output isn't captured or acted upon, their effects might not be noticeable.

## Conclusion:
Through this simple JavaScript code, we've illustrated how functions can be used to represent individual tasks within a broader process. Each function encapsulates a specific action, and by calling these functions in a sequence, we can simulate a morning routine. However, remember that capturing and using the output of these functions is crucial for making the simulation more accurate and meaningful.

In the world of programming, understanding how functions work together and how their outputs can be harnessed is key to creating organized and efficient code structures.
