Function isPresent

isPresent(value: unknown): boolean

Reports whether a value is meaningfully populated: not null/undefined, not an empty string, and not NaN. Used to gate optional detail rows so blank fields are skipped in the panel.

Parameters

value: unknown
The value to test.

Returns boolean

true when the value is present and renderable, false otherwise.

Example

isPresent("NaCl"); // => true
isPresent("");     // => false
isPresent(NaN);    // => false
isPresent(undefined); // => false
