lodash.omit

What is lodash.omit?

The lodash.omit package is a utility library that allows you to create a new object by omitting specified properties from an existing object. This can be particularly useful for removing sensitive information, simplifying objects, or preparing data for certain operations.

What are lodash.omit's main functionalities?

Omitting Single Property

This feature allows you to omit a single property from an object. In the example, the property 'a' is omitted from the object.

const omit = require('lodash.omit');
const object = { 'a': 1, 'b': 2, 'c': 3 };
const result = omit(object, ['a']);
console.log(result); // { 'b': 2, 'c': 3 }

Omitting Multiple Properties

This feature allows you to omit multiple properties from an object. In the example, the properties 'a' and 'c' are omitted from the object.

const omit = require('lodash.omit');
const object = { 'a': 1, 'b': 2, 'c': 3, 'd': 4 };
const result = omit(object, ['a', 'c']);
console.log(result); // { 'b': 2, 'd': 4 }

Omitting Properties Using a Function

This feature allows you to omit properties based on a function. In the example, properties where the key is 'a' or the value is 3 are omitted.

const omit = require('lodash.omit');
const object = { 'a': 1, 'b': 2, 'c': 3, 'd': 4 };
const result = omit(object, (value, key) => key === 'a' || value === 3);
console.log(result); // { 'b': 2, 'd': 4 }
