Lodash - omitBy method

Syntax

_.omitBy(object, [predicate=_.identity])

The opposite of _.pickBy; this method creates an object composed of the own and inherited enumerable string keyed properties of object that predicate doesn't return truthy for. The predicate is invoked with two arguments: (value, key).

Arguments

• object (Object) − The source object.

• [predicate=_.identity] (Function) − The function invoked per property.

Output

• (Object) − Returns the new object.

Example

var _ = require('lodash');
var object = { 'a': 1, 'b': '2', 'c': 3 };
var result = _.omitBy(object, _.isNumber);

console.log(result);

Save the above program in tester.js. Run the following command to execute this program.

Command

{ b: '2' }
