Package description
The lodash.includes package is a utility library that provides a method to check if a value is present in a collection (array, string, or object). It is a part of the larger Lodash library, which is known for its utility functions for common programming tasks.
Check if a value is in an array
This feature allows you to check if a specific value is present in an array. In the example, it checks if the number 3 is in the array [1, 2, 3, 4].
const includes = require('lodash.includes');
const array = [1, 2, 3, 4];
const result = includes(array, 3);
console.log(result); // trueCheck if a value is in a string
This feature allows you to check if a substring is present in a string. In the example, it checks if the substring 'world' is in the string 'hello world'.
const includes = require('lodash.includes');
const string = 'hello world';
const result = includes(string, 'world');
console.log(result); // trueCheck if a value is in an object
This feature allows you to check if a value is present in an object. In the example, it checks if the value 2 is in the object { 'a': 1, 'b': 2, 'c': 3 }.
const includes = require('lodash.includes');
const object = { 'a': 1, 'b': 2, 'c': 3 };
const result = includes(object, 2);
console.log(result); // trueUnderscore is a JavaScript library that provides utility functions for common programming tasks. It includes a method called 'contains' which is similar to lodash.includes. However, Lodash is generally considered to be faster and more feature-rich compared to Underscore.
Ramda is a functional programming library for JavaScript. It provides a method called 'includes' which is similar to lodash.includes. Ramda focuses more on functional programming paradigms and immutability, whereas Lodash provides a broader range of utility functions.
array-includes is a small, focused package that provides a method to check if a value is present in an array. It is similar to lodash.includes but is limited to arrays only. It is a lightweight alternative if you only need to work with arrays.
