What is JavaScript XML?

Imagine you're a chef creating a recipe card for a delicious cake using two different languages: JavaScript and HTML.

JavaScript: This is the language you use to define the logic and behavior of your recipe. It's like the ingredients and instructions for your cake. But, just like a recipe, it's not very visually appealing on its own.

const ingredients = ["flour", "sugar", "eggs", "butter", "vanilla"];

function mixIngredients(ingredients) {
    // Mixing logic here
}

HTML: This is the language you use to describe how your cake should look. It's like the decoration and presentation instructions. This is where you make your cake visually appealing.

<div class="cake">
    <h1>Delicious Cake</h1>
    <ul>
        <li>Flour</li>
        <li>Sugar</li>
        <li>Eggs</li>
        <li>Butter</li>
        <li>Vanilla</li>
    </ul>
</div>

Now, JSX combines the best of both worlds. It lets you write the visual structure of your UI elements using HTML-like syntax directly within your JavaScript code. This is like having your recipe and decoration instructions in the same language.

function Cake() {
    const ingredients = ["flour", "sugar", "eggs", "butter", "vanilla"];
    return (
        <div className="cake">
            <h1>Delicious Cake</h1>
            <ul>
                {ingredients.map(ingredient => (
                    <li>{ingredient}</li>
                ))}
            </ul>
        </div>
    );
}

In the JSX example, we define a Cake component using JSX syntax. It looks almost like HTML but is embedded within the JavaScript code. The {} curly braces are used to embed JavaScript expressions within JSX, enabling dynamic content.
