The Lodash _.dictionary() method returns a function that will attempt to look up a field that it is given.
Syntax:
funct = _.dictionary( object );
Parameters: This method accepts single parameter as mentioned above and described below:
- object: This method takes the object from which the field is to be searched.
Return Value: This method returns a function that will attempt to look up a field that is given.
Note: This will not work in normal JavaScript because it requires the lodash.js contrib library to be installed. Lodash.js contrib library can be installed using npm install lodash-contrib.
