If you'll be using a template more than once, it's more efficient to compile it

into a function once using `compile()`, and then render it whenever you need to
1960
by simply executing the compiled function. However, if you only need to compile
1961
and render a template once, `render()` is a handy shortcut for doing both in a

Precompiles a Handlebars template string into a string of JavaScript code. This
2005
can be used to precompile a template at build time or on the server, and the
2006
resulting template can then be rendered at runtime or on the client without
2007
needing to go through a compile step.

To render a precompiled template, evaluate the code and then pass the resulting

function to `Y.Handlebars.template()` to get back an executable template
