Common Mistakes

Using different delimiter names at start and end.

Not using the tilde (~) to enable indentation stripping.

The <<~END syntax allows indentation to be stripped from the heredoc content.

Common Mistakes

Using quotes around the delimiter.

Using lowercase delimiter which is uncommon and may cause confusion.

The delimiter must be an unquoted identifier and match exactly at start and end.

4fill in blank

Using double quotes which enable interpolation.

Omitting the tilde which keeps indentation.

Using <<~'END' disables interpolation (due to single quotes) and strips indentation (due to ~).
