func MapLookup ¶

func MapLookup(mapToLookup map[string]interface{}, keys ...string) interface{}

MapLookup traverses a nested map[string]interface{} using a sequence of keys.

Given a root map and a variadic list of keys, MapLookup attempts to follow the path described by the keys through nested maps. If the full path exists, it returns the value found at the end of the path. If any key is missing or a value along the path is not a map[string]interface{}, it returns nil.

Example usage:

m := map[string]interface{}{
    "a": map[string]interface{}{
        "b": map[string]interface{}{
            "c": 42,
        },
    },
}
v := MapLookup(m, "a", "b", "c") // v == 42

Parameters:

• mapToLookup: the root map to search
• keys: a variadic list of keys representing the path to traverse

Returns:

• The value at the end of the key path if found, or nil otherwise.
