/**
The `let` helper receives one or more positional arguments and yields
them out as block params.
This allows the developer to introduce shorter names for certain computations
in the template.
This is especially useful if you are passing properties to a component
that receives a lot of options and you want to clean up the invocation.
For the following example, the template receives a `post` object with
`content` and `title` properties.
We are going to call the `my-post` component, passing a title which is
the title of the post suffixed with the name of the blog, the content
of the post, and a series of options defined in-place.
```handlebars
{{#let
(concat post.title ' | The Ember.js Blog')
post.content
(hash
theme="high-contrast"
enableComments=true
)
as |title content options|
}}
{{my-post title=title content=content options=options}}
{{/let}}
```
@method let
@for Ember.Templates.helpers
@public
*/
export function blockLetMacro(params, _hash, template, _inverse, builder) {
if (template !== null) {
if (params !== null) {
builder.compileParams(params);
builder.invokeStaticBlock(template, params.length);
}
else {
builder.invokeStatic(template);
}
}
return true;
}
