Search for key in deeply-nested objects.
$ yarn add deepsearchjssearch<T>(object: T, any> | Array<any>, searchTerm: string): P;object
Object to be searched
True
T = Record<any, any> | Array<any>
searchTerm
string to search for, a function that determines if an object key matches the query, or a regular expression to use for matching
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..)
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
