JavaScript Lexical Scope Explained shortly
Tags: javascript, webdev, programming, tutorial
Published: 2024-04-24 06:58:20

Hey there, JavaScript enthusiasts! Today, let's talk about lexical scope and why it's a big deal in the JavaScript world.

So, lexical scope is all about how variables are handled in your code. It basically means that the scope of a variable is determined by where it's declared in your code, rather than when it's actually used.

Let me break it down for you with a relatable example. Imagine you're building a cool e-commerce website. You've got this function called `calculateTotalPrice` that does exactly what it says - it calculates the total price of a customer's shopping cart. Inside this function, you've got a variable called `taxRate`, which represents the percentage of tax applied to the total price.

Here's a snippet of what it might look like:

```javascript
function calculateTotalPrice(items) {
  const taxRate = 0.1; // 10% tax rate
  let totalPrice = 0;

  for (let item of items) {
    totalPrice += item.price;
  }

  const totalWithTax = totalPrice * (1 + taxRate);

  return totalWithTax;
}
```

In this example, `taxRate` is declared within the `calculateTotalPrice` function. This means that the scope of `taxRate` is limited to that function and any nested functions or blocks inside it. It can't be accessed from outside the function.

Now, let's say you want to calculate the total price including tax for different customers, but with different tax rates. You can create another function called `calculateTotalWithTax` that takes both the items and the tax rate as parameters.

Here's what that might look like:

```javascript
function calculateTotalWithTax(items, taxRate) {
  let totalPrice = 0;

  for (let item of items) {
    totalPrice += item.price;
  }

  const totalWithTax = totalPrice * (1 + taxRate);

  return totalWithTax;
}
```

In this case, the `taxRate` parameter is declared within the `calculateTotalWithTax` function. This creates a new scope for the variable, separate from the `taxRate` in the previous example. So now, you can provide different tax rates for different customers while still using the same function to calculate the total price with tax.

Understanding lexical scope allows you to organize your code better and control how variables are accessed and used based on where they're declared. It helps you avoid conflicts with variable names and provides a clear and predictable way to handle variables.

I hope this real-world example helps you grasp the idea of lexical scope in JavaScript. By embracing it, you'll be able to write cleaner and more maintainable code.

What are Classes and How to Use Them in JavaScript ? 🤔🤔
Tags: webdev, javascript, beginners, programming
Published: 2024-04-24 06:33:02


JavaScript, prior to ES6 (ECMAScript 2015), relied on constructor functions to mimic object-oriented concepts. These functions act as blueprints for creating objects, but lack some of the features and structure offered by modern classes.
Let's see a basic implementation of a constructor function for reference...

```
function Person(name) {
  this.name = name;
  this.greet = function() {
    console.log("Hello, my name is " + this.name);
  };
}
const person1 = new Person("Sandeep");

person1.greet(); // Output: "Hello, my name is Sandeep"
```


Now the question is if we already have something like this why to introduce something new, why to introduce classes, well thing is these functions have some limitations for example:-

No Inheritance: While you can mimic inheritance patterns using prototypes, it's less straightforward compared to classes.
Verbosity: Defining methods within the constructor function can lead to repetitive code, especially for complex objects.

that is why Classes were introduced in ES6 to  addressed these shortcomings by providing a more structured and concise way to define objects and their behaviour.

Well Now enough with why they were introduced and let's jump into how to use them properly.

To create a class all you have to do is use a keyword to define it which is called (wait for it, wait for it, drum roll please 🥁 🥁) "class" lol 🤣🤣. Here is a code snippet of a class in action.

```
class Person{
    constructor(name){
        this.name=name;
    }
    greet(){
        return `Hello, my name is ${this.name}`
    }
}

const sandeep = new Person("sandeep");

console.log(sandeep.greet()); 
//Output:'Hello, my name is sandeep'
```

Here are some key benefits of using classes in JavaScript:

- **Reusability**: Classes allow you to create multiple objects with the same structure and functionality, reducing code duplication.

- **Maintainability**: Code is easier to understand and modify when it's organised into classes. Each class encapsulates its own data and logic, making it more self-contained.

- **Object-Oriented Patterns**: Classes facilitate the use of common object-oriented design patterns like inheritance and polymorphism ✨

Now your next question will be "Sandeep, we got it, why classes were introduced and how to implement them, but where to implement them? Well, that's something we will discuss in the next article. Until then, happy coding!"

I hope this helps! 😁😁
