Markdown Code block's basic and advanced syntaxes

Basic syntax

Use triple backticks to create a code block in markdown

```language
your code goes here
```

Example

```javascript
function debounce(func, timeout = 300) {
  let timer;
  return (...args) => {
    clearTimeout(timer);
    timer = setTimeout(() => { func.apply(this, args); }, timeout);
  };
}
```

will appear as:

function debounce(func, timeout = 300) {
  let timer
  return (...args) => {
    clearTimeout(timer)
    timer = setTimeout(() => {
      func.apply(this, args)
    }, timeout)
  }
}

Filename

Add :filename.ext after language to render with filename label on the top of block

Example:

```java:GetRowValue.java
private String[] getRowValue(Integer i, List<BillDetail> billDetail) {
  String[] rowValue = new String[5];
  rowValue[0] = (i).toString();
  i = i - 1;

  rowValue[1] = billDetail.get(i).getTenSanPham();
  rowValue[2] = billDetail.get(i).getSoLuong().toString();
  rowValue[3] = new DecimalFormat("#,###").format(Integer.parseInt(billDetail.get(i).getDonGiaSanPham()));
  rowValue[4] = new DecimalFormat("#,###").format(billDetail.get(i).getThanhTien());
  return rowValue;
}
```

will appear as:

GetRowValue.java

private String[] getRowValue(Integer i, List<BillDetail> billDetail) {
  String[] rowValue = new String[5];
  rowValue[0] = (i).toString();
  i = i - 1;

  rowValue[1] = billDetail.get(i).getProductName();
  rowValue[2] = billDetail.get(i).getQuantity().toString();
  rowValue[3] = new DecimalFormat("#,###").format(Integer.parseInt(billDetail.get(i).getProductPrice()));
  rowValue[4] = new DecimalFormat("#,###").format(billDetail.get(i).getSubTotal());

  return rowValue;
}

Line highlighting and line-numbers

Add {numbers} property after language to highlight line
Add showLineNumbers property after language to render with line numbers

Example:

```html {1,4-6,10} showLineNumbers
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Hello world</title>
  </head>
  <body>
    <h1>Hello world</h1>
  </body>
</html>
```

will appear as:

<!doctype html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <meta http-equiv="X-UA-Compatible" content="ie=edge" />
    <title>Hello world</title>
  </head>
  <body>
    <h1>Hello world</h1>
  </body>
</html>
