/**
|
|
* This function retrieves the names of string-keyed properties from an object, including those inherited from its prototype.
|
|
*
|
|
* - If the value is not an object, it is converted to an object.
|
|
* - Array-like objects are treated like arrays.
|
|
* - Sparse arrays with some missing indices are treated like dense arrays.
|
|
* - If the value is `null` or `undefined`, an empty array is returned.
|
|
* - When handling prototype objects, the `constructor` property is excluded from the results.
|
|
*
|
|
* @param [object] - The object to inspect for keys.
|
|
* @returns An array of string keys from the object.
|
|
*
|
|
* @example
|
|
* const obj = { a: 1, b: 2 };
|
|
* console.log(keysIn(obj)); // ['a', 'b']
|
|
*
|
|
* const arr = [1, 2, 3];
|
|
* console.log(keysIn(arr)); // ['0', '1', '2']
|
|
*
|
|
* function Foo() {}
|
|
* Foo.prototype.a = 1;
|
|
* console.log(keysIn(new Foo())); // ['a']
