Code Blocks

Code blocks can be used to display multiple lines of code. They preserve formatting and provide syntax highlighting when possible.

Basic Usage

To create a basic code block, wrap the code with three backticks (```):

```
This is a code block.
```

The result will look like this:

This is a code block.

An alternative way to create a code block is by adding four spaces before each line of code:

[space][space][space][space]This is a line of code.
[space][space][space][space]This is a line of code.

The result will look like this:

    This is a line of code.
    This is a line of code.

However, the recommended way to create a code block in GitHub Markdown is using triple backticks (```).

Syntax Highlighting

Optionally, a language can be specified for a code block to enable syntax highlighting. This can be done by appending the language to the starting backticks. The indent lines method (four spaces) does not support syntax highlighting, so using the former method is preferred:

```js
console.log('Hello world');
```

The result will look like this:

console.log('Hello world');
