Lodash _.omitBy() Method

Lodash _.omitBy() method is used to return a copy of the object composed of the own and inherited enumerable string keyed properties of the object that the predicate doesn't return truthy for. It is the opposite of _.pickBy() method.

Syntax:

_.omitBy( object, [predicate] );

Parameters:

• object: This parameter holds the source object.
• predicate: This parameter holds the function that is invoked for every property. It is an optional value.

Return Value:

This method returns the new object.

Example 1: In this example, we are omitting those values which do not support the _.isLength() method and returning the rest of the element as an object.

Output:

{Name: "GeeksforGeeks", username: "your_geeks"}

Example 2: In this example, we are omiting those values which do not support the _.isNumber() method and returning the rest of the element as an object.

Output:

{'y': '2'}
