isArrayLikeObject
INFO
This function is only available in es-toolkit/compat
for compatibility reasons. It either has alternative native JavaScript APIs or isn’t fully optimized yet.
When imported from es-toolkit/compat
, it behaves exactly like lodash and provides the same functionalities, as detailed here.
Check if a value is a non-primitive, array-like object.
An array-like object is an object that is not null
or undefined
or a function, and has a length
property that is a valid length.
This function can also serve as a type predicate in TypeScript, narrowing the type of the argument to ArrayLike<unknown> & object
.
