trim

Removes whitespace from both ends of the string. The result goes to data.

Signature

function trim(): Action<string>

Notes

• Order matters: put trim() before length checks.
• A whitespace-only string becomes '' after trim(), but there is no required error — the emptiness check has already passed. Add minLength(1).

Example

Name

pipe(string(), trim(), minLength(1, 'Please enter your name'))
