Description
This PR improves the Callback function glossary page by clarifying the examples that illustrate synchronous vs asynchronous callbacks.
console.log(value)prints2(becausevalue = 2has already run).Motivation
The previous example was incomplete and sometimes confusing for readers.
I’ve received feedback that when sharing the page, the example “didn’t work” for people who had not yet read other parts of the documentation, because the context was missing.
These changes make the examples self-contained and explicit, so they work for first-time readers as well as those familiar with other MDN docs.
