<h3>Using a hash</h3>

{{#with-hash/yield-to-block as |data|}}
  {{data.child}}
{{/with-hash/yield-to-block}}

<h3>Not using a hash</h3>

{{#without-hash/yield-to-block as |child|}}
  {{component child}}
{{/without-hash/yield-to-block}}

<h2>Passing a component into another</h2>

<p>In these exampls, a parent component is given a child component to render</p>

<h3>Using a hash</h3>

{{with-hash/pass-as-property
    data=(hash
			child=(component 'child-component'))
}}

<h3>Not using a hash</h3>

{{without-hash/pass-as-property
		child=(component 'child-component')
