 ## Pre-Compiling Templates
 
-When using in-DOM templates or in-JavaScript template strings, the template-to-render-function compilation is performed on the fly. This is usually fast enough in most cases, but is best avoided if your application is performance-sensitive. The easiest way to pre-compile templates is using [Single-File Components](./single-file-components.html) - the associated build setups automatically performs pre-compilation for you, so the built code contains the already compiled render functions instead of raw template strings.
