Block Append and Prepend

When using inheritance and blocks, sometimes we want to add to the content instead of overwriting it. We can do so with the "append" and "prepend" keywords. Either by itself along with the block name, or as a parameter to the "block" keyword.

Example: if we have the parent template base.jade:

// base.jade
h1 Hello from the base
block content
    p Welcome

And we want our child to append to the content block:

// child.jade
extends base
block append content
    p And goodbye

This will output:

<h1>Hello from the base</h1>
<p>And goodbye</p>

As mentioned you can skip the block keyword and just use append or prepend.

// child.jade
extends base
append content
    p And goodbye
