 This proposal introduces a new magic comment that signals to browsers that the functions in a JavaScript file are likely to be needed by the website. This allows the browser to parse and compile them eagerly, which can improve page load times.
 
+In this example, the magic comment is used for triggering the eager compilation of the two JavaScript functions in the file:
+```JavaScript
+//# eagerCompilation=all
+
+function foo() { ... } // will now be eagerly parsed and compiled
+function bar() { ... } // will now be eagerly parsed and compiled

 ### On JavaScript parsing and compilation
 
 Knowing which JavaScript functions to parse and compile during the initial script compilation can speed up web page loading.

 ```JavaScript
 //# eagerCompilation=all
-
-function foo() { ... } // will now be eagerly parsed and compiled
-function bar() { ... } // will now be eagerly parsed and compiled
 ```
 
 The magic comment is intended as a hint to the browser. It signals the functions in this JS file should be treated as "high priority" - for example, compile them immediately when processing the script, as opposed to when a function is called.
