lastNWords

Import from @varavel/vdl-plugin-sdk/utils/strings.

function lastNWords(
   str, 
   n, 
   ellipsis?): string;

Returns the last n normalized words from a string.

Word boundaries are determined by the shared words tokenizer, which makes this helper suitable for preview text, normalized identifiers, and compact labels derived from mixed-case or separator-heavy inputs.

When truncation happens, an ellipsis is appended by default. Non-positive and non-finite lengths return an empty string.

Parameters

Parameter	Type	Default value	Description
`str`	`string`	`undefined`	Source string to tokenize and shorten.
`n`	`number`	`undefined`	Maximum number of trailing words to keep.
`ellipsis`	`boolean`	`true`	When `true`, appends `...` if truncation occurs.

Returns

string

The trailing normalized words, optionally suffixed with an ellipsis.

Example

lastNWords("HTTPServer_URL-v2", 2);
// "URL v2..."
