Syntax Of Lodash drop Right While method

_.dropRightWhile(array, [predicate=_.identity])

The Lodash drop Right While method Creates a slice of array excluding elements dropped from the end. Elements are dropped until the predicate returns false. The predicate is invoked with three arguments: (value, index, array).

Arguments

• array (Array) − The array to query.
• [predicate=_.identity] (Function) − The function invoked per iteration.

Output

• (Array) − Returns the slice of array.

Example

var _ = require('lodash');
var users = [
   { user: 'Sam', active: false },
   { user: 'Ted', active: true },
   { user: 'Julie', active: false }
];

var result = _.dropRightWhile(users, function(user) { return !user.active; });
console.log(result);

result = _.dropRightWhile(users, ['active', false]);
console.log(result);
