Lodash: Delete unwanted properties from the javascript object

lodash__black_list_white_list.js

You can approach it from either a white list or black list way:

// Black list
// Remove the values you don't want
var result = _.omit(credentials, ['age']);

// White list
// Only allow certain values
var result = _.pick(credentials, ['fname', 'lname']);
If it's reusable business logic, you can partial it out as well:

// Partial out a black list version
var clean = _.partial(_.omit, _, ['age']); 

// and later
var result = clean(credentials);
