Note the implode and list aliases on the join modifier page

[joshdaugherty]

The join modifier is registered under three names: join, implode and list all map to joinplode in ExtensionServiceProvider. The Join page doesn't mention the other two, so a search for implode (the name of the PHP function) finds nothing.

list already has its own page, which links to Join, but implode isn't documented anywhere. This adds one line to the Join page naming both aliases, in the same form the Option List page uses for piped.

Checked on statamic/cms v6.26.0: with t set to ["a", "b", "c"], {{ t | implode }}, {{ t | list }} and {{ t | join }} all render a, b, c, and {{ t | implode(" + ") }} renders a + b + c.
