What is the alternative angular bracket notation? Can somebody gives me an example of it?
The alternative angular bracket notation is called the JSX syntax, which is commonly used in the React JavaScript library. JSX allows you to write HTML-like code alongside JavaScript code, which makes it easier to build user interfaces.
To use JSX, you need to have Babel or a similar transpiler set up, as JSX is not valid JavaScript syntax on its own. The transpiler will convert the JSX code into regular JavaScript that the browser can understand.
Here's an example of using JSX:
```jsx
const element = <h1>Hello, World!</h1>;
```
In this example, we're creating a variable called `element` and assigning it a JSX expression. The expression looks like HTML code, but it's actually JSX. The angle brackets `<h1>` and `</h1>` represent an HTML `<h1>` element.
When the transpiler converts this code, it will generate the equivalent JavaScript code:
```javascript
const element = React.createElement("h1", null, "Hello, World!");
```
In this JavaScript code, the `React.createElement()` function is called to create a virtual representation of the HTML element with the specified tag name and content.
So, in summary, the alternative angular bracket notation is JSX, a syntax extension that allows you to write HTML-like code in JavaScript React applications.
