  1942 
       
  1943 If you'll be using a template more than once, it's more efficient to compile it
       
  1944 into a function once using `compile()`, and then render it whenever you need to
       
  1945 by simply executing the compiled function. However, if you only need to compile
       
  1946 and render a template once, `render()` is a handy shortcut for doing both in a
       
  1947 single step.
