nonObjectLike
function nonObjectLike<T>(value: T | object): value is T;
nonObjectLike(value) is the same test as !isObjectLike(value), written so that a guard clause reads as a sentence rather than as a negation.
Everything isObject accepts, plus functions: the question it answers is whether properties can be read off the value at all.
isX and nonX answer a question and never interrupt control flow; requireX and requireNonX hand the value back or throw. The scheme is explained in Validation conventions.
Parameters
Parameter | Type | Description |
|---|---|---|
|
| The value to check. |
Returns
boolean — true when the value is not object-like; otherwise false.
In TypeScript the guard narrows value to T inside the branch.
