NameDescriptionRequiredType

object

Object to be searched

True

True

string or ((key: string, value: any) => boolean) or RegExp

output

Output object

---

P = Record<key: string, any> Where, key is a valid object path(eg. a.b.c[0].d.e, etc..)

Parameters

  • obj (T): The object to search. It is also generic, meaning it can accept any type of object.

  • query (string | ((key: string, value: any) => boolean) | RegExp): The query to search for. This can be a string, a function, or a regular expression.

    • If it is a string, the function will search for keys that end with that string.

    • If it is a function, it will determine if the key matches the query.

    • If it is a regular expression, it will test the key against that regular
