The `Bun.escapeHTML()` utility can be used to escape HTML characters in a string. The following replacements are made.
- `"` becomes `"""`
- `&` becomes `"&"`
- `'` becomes `"'"`
- `<` becomes `"<"`
- `>` becomes `">"`
This function is optimized for large input. Non-string types will be converted to a string before escaping.
```ts
Bun.escapeHTML("<script>alert('Hello World!')</script>");
// <script>alert('Hello World!')</script>
```
