+## API
+
+### get(object, path, defaultValue?)
+
+### set(object, path, value)
+
+Returns the object.
+
+### has(object, path)
+
+### delete(object, path)
+
+Returns a boolean of whether the property existed before being deleted.
+
+#### object
+
+Type: `object`
+
+Object to get, set, or delete the `path` value.
+
+You are allowed to pass in `undefined` as the object to the `get` and `has` functions.
+
+#### path
+
+Type: `string`
+
+Path of the property in the object, using `.` to separate each nested key.
+
+Use `\\.` if you have a `.` in the key.
+
+The following path components are invalid and results in `undefined` being returned: `__proto__`, `prototype`, `constructor`.
+
+#### value
+
+Type: `unknown`
+
+Value to set at `path`.
+
+#### defaultValue
+
+Type: `unknown`
+
+Default value.
