Inconsistency in spelling conventions can lead to several issues:

* **Confusion for users and contributors**: Mixed spellings (e.g., "color" and "colour", "initialize" and "initialise") in the codebase create confusion about which variant to use

**Exception Handling:**
```java
try {
    converter.init();
} catch (Exception e) {
    throw new SuggesterException("Failed to initialize converter: "
                                + converter.getClass().getName(), e);
}
```

**Resource Management:**
```java
try (InputStream is = getClass().getClassLoader()

To add a function that should be run before the application starts, declare it with the event `"startup"`:

{* ../../docs_src/events/tutorial001_py39.py hl[8] *}

In this case, the `startup` event handler function will initialize the items "database" (just a `dict`) with some values.

You can add more than one event handler function.

And your application won't start receiving requests until all the `startup` event handlers have completed.
